Java programming courses 1 year. Java programming training. What will I receive upon completion of training?

Moscow is a huge metropolis. This means that almost everything is here. Programming courses in Moscow can be found to suit every taste, but such variety does not make it any easier for a beginner. A reasonable question arises: what principle should we use to search for? Who can you trust with your education? In this article, we will not consider universities as a source of knowledge and skills for a future programmer, but will talk about private courses. About what they are, what their features are and what you should pay attention to when choosing.

Courses can be divided into face-to-face (offline) and online.

Full-time form of education

Paid programming courses

First, let's look at paid Java courses in Moscow. They involve working in computer class with a teacher plus homework. Typically, a student must write 1 to 3 programming problems per week. Everything is approximately the same as in a university, only the audience is usually smaller and, theoretically, there is more attention to each student.

Location

Everyone who lives in the capital knows that the first question that needs to be clarified is where the programming courses are located geographically; Moscow is big. If you are lucky enough to find a school close to your place of work or residence, then you can take a closer look at the following factors. If not... Even serious people sometimes drop out of school after missing classes several times in a row due to two-hour traffic jams.

Visiting schedule

Typically, two weekday evenings after work are set aside for classes. Classes last 2-3 hours. Some programming courses in Moscow offer weekend groups. Perhaps this is convenient: your head is clearer, there are fewer traffic jams. However, this option is most often not suitable for family people.

Computer classes

Before starting classes, you need to clarify whether the courses offer computers or whether you need to bring your own laptop. The second option is becoming more common. This has its pros and cons. If you already carry your computer with you to work, then you won’t experience much discomfort, but if you don’t really want to take your iron friend with you on the subway, you may need to look for other options.

Teacher

A very important factor! Before you pay for the course, you need to know:
  1. Teacher qualifications. Is he a professional programmer or a technical university teacher who decided to earn a little extra money in the evenings? If he is a programmer, what company does he work for, what is his job title (Junior, Middle or Senior Java Developer)? It is advisable that you meet a person who knows the programming industry from the inside, and not from the stories of others.
  2. How busy is the teacher? Will the teacher have assistants or does he work alone? How many groups will this teacher lead at the same time? This is also important. Imagine: there are usually 10-15 people in a group, everyone needs to be checked homework. What if the teacher has many such groups? He physically will not be able to carefully study the code of each student.
  3. How long has he been working on these courses? If yes, try to find forums and reviews that they write about him: the combination “a good teacher (that is, someone who knows how to explain complex material well) + a good programmer” is very rare. If you suddenly find one like this, consider yourself very lucky.

Price

The number of treasury notes that you will have to pay for programming courses in Moscow depends primarily on the previous point. That is, on the qualifications and requests of the teacher. A good Middle level programmer earns at least $2,000 a month, feel free to multiply by two if he is Senior. As you understand, it is not easy to interest such a person in a part-time job. If your teacher is a recent student himself, then the courses will be cheaper, but the quality... However, we won’t judge. There are natural teachers who simply really enjoy teaching. Such people can earn a lot from their main job, and consider teaching as their hobby.

Training program

Typically, one programming course, for example “Java from scratch,” lasts 2-3 months, and 1-2-3 such courses are offered. Two classes per week, 2-3 assignments the same week. This is approximately 36 tasks per course - for a beginning programmer this is catastrophically small. Almost any educational company offers programming courses from scratch; in Moscow there are a lot of such courses for beginners. But if you already have some experience, the choice narrows sharply. The reason is still the same: there are too few programmers ready to teach. And while courses for beginners can still be taught by a green teacher or computer science professor, this won’t work with “continuing” students. Total advantages:
  • Personal communication with a teacher-programmer (if you’re lucky);
  • Equally personal interaction with other students;
  • There is a training program that you can “follow”.
Flaws:
  • You need to spend time traveling to the courses;
  • A strict schedule that is easy for a working person to fall behind;
  • Few practical tasks;
  • Often - high price or low quality of courses;
  • Usually there is a high workload of teachers.
Of course, we provide only generalized advantages and disadvantages of full-time courses. If you are lucky enough to find courses with a good teacher and a convenient location, the disadvantages will immediately be leveled out.

Courses/internships at companies

Courses offered by IT companies are very different from the face-to-face courses we discussed above. Typically, these courses are unpaid (and sometimes paid) internships. Typically, large IT companies recruit for such courses several times a year. This is very useful, and Moscow residents should monitor such events. Only you need to apply for them, and this is not easy, since there are a lot of candidates for each place. And one more important point: such courses are designed for so-called “experienced beginners”, in fact, almost ready-made Junior Developers without real work experience. Accordingly, such courses usually last six months. They are very complex and require a lot of dedication. By the end, ⅔ of the original group is eliminated. As a result, the best ones can be hired for a full-time job, on a “junior” salary. Advantages of courses provided by companies:
  • Free;
  • Teachers are active programmers;
  • A lot of relevant practice (that which is needed in modern IT);
  • Almost real experience of working in an IT company;
  • A chance to get a job in a company.
Disadvantages (from the position of beginners):
  • To enroll in courses, you need to be an almost ready programmer and go through a difficult selection process;
  • Huge workload (often incompatible with the main job);

Form of study: online courses

Group online programming courses

This type of course is not much different from full-time courses. We have the same 2 classes per week in strict certain time during three months. Only a group of students and a teacher gather not in a classroom, but each at his own computer. Everything else is the same. Probably, such courses are preferable for busy Muscovites: at a minimum, the problem of wasting time and nerves on the road to a programming school disappears. In addition, these courses can be somewhat cheaper than full-time courses, since their organizers do not need to spend money on renting classrooms and purchasing equipment. There is another option for online group courses. Students are not watching lectures in live, and recordings of webinars, and at a certain time the teacher conducts a series of consultations on theory and homework. Advantages:
  • No need to waste time and money on the road
  • Communication with the teacher and other students
Flaws:
  • Same as full-time courses (except travel time)

Individual online Java courses in Moscow

These courses are somewhat similar to mentoring, so they are usually expensive. As a rule, you follow the program compiled by the teacher, listen to recordings of his lectures, do homework, get them checked and short personal consultations. A good and flexible option: there is no longer a strict connection to class time, you watch lectures when it is convenient for you and agree with the teacher about a consultation at a time convenient for you. Advantages:
  • Personal lesson schedule
  • “Live” mentor
Flaws:
  • High price
One can imagine a more budget-friendly option, in which one teacher is “shared” among a large number of students. Accordingly, not too much attention is paid to everyone (here it all depends on the responsibility of the course author). Tasks with this approach are very often checked with a simple autovalidator, in worse cases - by comparison with other people's code on GitHub.

“Platform” online courses

Platforms Coursera, Udemy, edX and others contain a huge number of programming courses. Among them are many free ones, recorded by masters of their craft (the same “Harvard CS50. Fundamentals of Programming” in English is on edX, and the JavaRush website has a Russian version of this most popular course for beginners). Some platforms have an approximate schedule for completing courses (most often, tasks are divided into weeks) and it is better not to deviate from this schedule. Typically, such courses consist of videos, additional materials, tests and homework. Sometimes tasks can be verified using simple built-in validators, but most often the correctness of the code cannot be reliably verified. Advantages:
  • Flexible schedule
  • Often free or not very expensive
Flaws:
  • Lack of feedback, which is why students most often drop out of such courses;
  • Few practical tasks.

Special Java courses: JavaRush

JavaRush is up to the Java Junior Developer level.

The course is divided into 4 blocks (quests), each of which has 10 levels. While taking the course, you will computer game, move from level to level, thereby improving your knowledge and programming skills. Each level contains several short text lectures written in the form of dialogue from highly original characters, as well as many tasks. Only by solving most of the problems in the level will you gain enough points (here they are called “dark matter”) to move on. Each task has a list of requirements, making it easier for beginners to understand. Also built into the course automatic check solutions and a recommendation system - a kind of “virtual mentor”. You simply click on a button and the solution is sent to the “mentor”. A moment later, a response comes in which you receive information about the correctness of the decision and a list of recommendations on how to correct errors, if any. So, attention: there are more than 1200 such tasks in JavaRush! Their elaboration is that very valuable first programming experience that beginners so lack. Because of this feature, teachers of face-to-face or online courses often recommend JavaRush as a source of additional tasks. Most of the problems are fairly simple, but starting midway through the course, JavaRush offers mini-projects—large problems with step-by-step instructions that help students create their first complex programs. For example, the game 2048 or a restaurant emulator. Depending on the student’s workload and his skills before the start of the course, JavaRush can be completed in a period of 3 months to a year. After completing the course, you can sign up for an online internship, learn the Java EE technology stack, and create your own project. Those who are looking for courses very often fear that there is no meaningful feedback in the online environment, which makes serious problems almost unsolvable. JavaRush successfully copes with this problem with the help of the JavaRush community and the “Help” section, where you can ask questions about tasks and theory. Students' questions are usually answered fairly quickly. This is done either by other students or someone from the JavaRush team.

conclusions

It's up to you to draw your own conclusions! Regardless of anything, we wish you to find the best programming courses in Moscow or online!
What else to read:

The programming language “Java” can be called the Esperanto language in the IT world. Java was invented in 1995 and since then its popularity has been growing inexorably, despite the emergence of a huge number of new modern programming languages. The secret of Java's popularity is its versatility and relative simplicity. “Write once, run anywhere,” which is why many large companies choose Java more often than any other language when ordering commercial projects.

I could talk for hours about the versatility of Java. Java is the lingva franca of programming. If you “speak” Java with some developers on the forum, there is a very high probability that even those who specialize in other languages ​​will understand you without translation.
As of 2018, there are more than 150 programming languages ​​in the world, but all of them, to some extent, take their origins from Java.

This popularity directly affects the demand and salaries of Java programmers. Only the people who manage them earn more than Java Developers.

Each module studies a specific cluster of theoretical and practical knowledge that will allow you to make a name for yourself in the world information technologies in just 6 months!

Training program modules are compiled by practicing specialists who know what to look for Special attention. The course goes “from small to large” and is designed for students who are starting from scratch. Each subsequent module is a logical continuation of the previous one. The curriculum allows you to build up your knowledge gradually.

If you have firmly decided to start learning programming, but don’t know which way to approach this issue, don’t know which language to choose and which IT industry to go into, then this course is for you! The course is designed to teach you the basics of programming from the very beginning. We will teach you to look at the program through the eyes of the Creator, and not the ordinary user.

Why are our Java courses so cool?

1. Everything in one place.

If you don’t know where to start learning java, then we will answer you “You need to start learning java by calling EasyUM.” We have compiled a super program of Java courses, comparable to studying to become a programmer at a university in terms of knowledge coverage. During the course you will learn all the necessary skills to work as a Java Junior.

2. In clear words.

Learning to program in Java at “EasyUM” is easy and relaxed. Our mentors have not forgotten how they felt at the beginning of their personal journey of learning to become a programmer, how they were lost in terms and abbreviations, so they will be happy to explain to you all the difficult and scary moments in simple and understandable words.

3. Combine the program yourself.

Our java courses are designed for everyone who wants to learn, from scratch to tangible results. However, if you are familiar with the syllabus of one of the modules, you can “remove” it from your training program.
Take a confirmation test according to the java course module program that you are familiar with and continue learning as efficiently as possible.

The main advantage of the “EasyUM” java courses is the emphasis on practice. The combination of theory and practice in a ratio of 20 to 80 allows all our students to immediately integrate into their studies, and the availability practical classes And laboratory work on each module will not allow you to miss “something” important from the training.

If you still don’t know where to start programming, “EasyUM” is waiting for you!

Many developers, having studied one programming language, decide to develop further and are inclined to programming in Java.

A Java developer must have solid knowledge of object-oriented programming and be able to write simple, readable code using design patterns. Java has many libraries and frameworks. Developers need to know them not only at the level of use, but also understand how these libraries and frameworks work internally.

Java programmers are in demand in areas where they use projects with multi-user data processing and high security requirements. A Java programmer typically develops the application architecture, application business logic, supports and maintains the project, and writes technical documentation.

JavaRush - learning Java programming as an online game


How about a completely new approach to learning programming and education in general? Unlike anything you've seen before. What about learning where there is a goal, a means and an outcome?

I'm glad to introduce you to new online courses learning programming in Java.

1 Training made in the form of an online game

You take a task, complete it and receive a reward. I think this is both understandable and familiar to you. The tasks will be very diverse: reading code, solving problems, video tutorials, watching Futurama, fixing errors in the code, adding new features and much more.

You might even have to write programs for your robot to fight your friends in an "arena" or something else.

2 Only the essentials

To prevent the course from stretching over 5 years, I threw out everything useful from it and left only the essentials. I analyzed dozens of vacancies on the labor market. The course includes all the topics a beginner needs to know Java Junior Developer to get a job.

3 I approached your training thoroughly

The complete course contains 900 mini-lectures and 2500(!) practical problems. The tasks are small, but there are many, many of them. Just the minimum that, if completed, will give you such valuable experience.

There is also pair work, various games, big problems, real projects and other types of practice.

4 You can't complete the game without becoming a programmer

The course is divided into 80 levels. You can move to the next level only if you have solved most of the problems in the current level. Starting with small and light ones, and ending with large and very useful ones. Everyone who makes it to the end will receive 500-1000 hours of practical experience. A serious bid for victory. And to work.

5 Purposeful preparation for an interview

The last 10 levels focus on resume writing, interview preparation, and teamwork skills. Video recordings of interviews and their analysis will be added. And, of course, typical interview questions with answers.

What are you learning?



For the first 40 levels you learn Java Core. The next 40 are the basics of technologies such as JSP, Servlets, Hibernate, Spring. The Java Core study is very detailed, everything else is in the minimum version that a Java Junior may need when applying for a job.

If there are large IT companies in your city, after level 40 you can try to get an internship with them. If there are none or you lack experience, you can continue learning Java technologies until you reach level 80.

At the end, a lot of time will be devoted to creating a resume, analyzing typical interview questions and recommendations for working in a team.

Course in development (25% done)



IN currently well is in development. About 25% of all work has already been done. It’s enough to try on the role of a Java programmer and evaluate both your strengths and JavaRush. Try it, maybe this small event will begin a series of magical changes in your life.

Future plans

Many features have already been made, many are still being worked on, and the rest is modestly waiting for its turn. Animation, educational games, and a non-linear development scenario will be added. The full course will include 80 levels, 900 lectures and two and a half thousand practical exercises. As well as video recordings of interviews and their analysis. Samples of resume writing and a convenient service for this.

Much will depend on your reviews and traffic to the service.

Why Silverlight?
The game is written in Silverlight. The training course was originally designed as an online game: a lot of animation, built-in mini-games, videos, cartoons and much more. So the choice here was between Silverlight (in which I have good experience) and Flash (in which I have much less experience).

Simple tasks can be solved on the website; for everything else there is MasterCard Intellij IDEA.

Programming is simple and interesting.

Payment

The service is currently free. At the same time, funds are needed for its successful development. A completed service is better than an abandoned one.
Educational grants
It wouldn't hurt much. I hope that my vision of education, described in the article “the right university,” will find a response in the hearts of like-minded people.
Also, I hope for your feedback. The more enthusiastic reviews the project receives, the more likely it is that some good foundation interested in the development of education will give us a development grant.
Freemium model
With this approach, the main functionality of the service is free. The development of the service is carried out using income received from additional paid services. This could be personal consultations, sets of specially written tasks, or deeper training on key topics. Also, for example, video lectures, video lessons, writing a resume, preparing for an interview.

Either I'm too optimistic or too naive, or one of the two.

What is the beauty of the era of online courses?

They will destroy the industry that is mistakenly called higher education. 

What about the university?



To get a job as a new Java programmer, you need to have a good knowledge of Java Core, the basics of basic frameworks (Hibernate, Spring, JSP, Servlets) and have at least several months of programming experience.

Formally, they teach you much of this in universities. In fact, almost none of the above.

All universities are different, so for simplicity, I will compare an average technical university with an average vacancy for a Junior Java programmer and write my vision of the resulting situation. This diagram should not be taken as the ultimate truth, but rather as a simplified view of things, in order to bring at least some clarity.

Java Junior Developer

This is most likely how things are when you have already graduated from college and are just looking for a job:

Everything that the university did not teach you, but that you need in your work, you will have to learn yourself. Most likely, according to the books, 6-12 months. If you have a programmer friend who is ready to be your mentor, this period can be reduced by 2-3 times.

It is also obvious that at university you studied a lot of things that you do not need when you first get a job. You may not need most of this knowledge right away, but will need it in the future. This is how the situation will change in 5 years.

A year ago, such a service was not even in the plans, and I had to train only a few people at a time. Now More than a thousand people use JavaRush and about a third of them practice every day.

So, those who have the desire, but do not have the opportunity - let's try.

I repeat. Currently the course is in development. About 25% of all work has been done (20 levels out of 80). It’s enough to try on the role of a Java programmer, as well as evaluate both your strengths and JavaRush.

Always yours, General

Personal details and friends
It is necessary in order to display the progress of you and your friends on a star map.

Your audio and video recordings
Futurama series are uploaded to VK. I show them directly from there.
(So ​​as not to overload my server with video distribution)

Working with a wall
So you can invite friends to learn Java with you.
(This can be done in the "Friends" section)

And nothing more.


I tested it only on Windows.

It doesn't seem to work on Linux with Moonlight.
No one has unsubscribed under MacOSX yet.



Why Silverlight was chosen

1 There is no connection between what language we learn and what the application for classes is written in
If I were writing an educational app for the iPad, I would write it in Objective C rather than Java
If I taught SQL, I wouldn't write a client in SQL either

2 Each language/framework has its own purpose
For Java, these are Android and Enterprise.
And for RIA applications, Flash & Silverlight are best suited

3 I have a lot of experience with Silverlight
Of all the technologies I know, I chose the one most suitable for online gaming.
If I didn't know Silverlight, but knew Flash well, the client would be in Flash.

4 There are a lot of IT workers on the hub who basically use Linux and do not use VK.
If you are an IT worker and only have Linux, you may have already outgrown the Java Junior course.

5 We should write everything in Java!
Are there too many demands for a project that started out simply as a desire to help people and a hobby?

6 I saw that Silverlight and immediately closed it
If the technology used to create a client outweighed all the advantages of the project for you, then maybe you didn’t really want it?
Those who want are looking for an opportunity (and I provided it), those who don’t want are looking for a reason.
