Java Programmer: Features, Advantages and Disadvantages, Study and Knowledge

Java is an object-oriented programming language developed by Sun Microsystems. It is quite difficult to learn, but programmers in this area make good money. Let's take a look at how to become a Java programmer and what skills and knowledge are required for this.

When talking about a programming language like Java, remember that it is one of the oldest and most complex, but at the same time multifunctional programming languages... Java cross-platform works on almost any device and with any operating system. It was used in writing applications for Google, Yandex, Mail. ru. About 3 billion programs are written on its "roots", with its help more than 2 billion phones and 125 million TVs are controlled.

The Java language is very multifunctional, its possibilities end where the imagination of a programmer writing in this programming language dries up... Java is an excellent tool, since libraries and functions on it can be created by the programmer himself, and then you can transfer them to any person or source. Many people confuse Java and JavaScript, which shouldn't be done. The former is mainly used for writing Android apps, while the latter is for front-end website and web application development.

The main feature of the work of Java programmers is the higher salary when compared with other specialists in the field.Also, a Java programmer is distinguished by his personal qualities, mathematical and logical warehouse, good memory, since a specialist of this type needs to memorize a lot. Among the responsibilities of a Java programmer are the following:

• personal contact with the customer and its maintenance during work;
• development of various software modules, as well as their architecture;
• testing new products and their application in practice;
• search for possible errors and their elimination;
• writing instructions for new products, paperwork.

As in any other profession, there are positive and negative sides here, which we will now consider.

Advantages:

• high salary: from 70 to 120 thousand rubles;
• a huge number of jobs (demand);
• luxurious conditions within the walls of the office: free meals, a powerful personal computer, insurance, a comfortable workplace;
• the ability to work remotely, while earning even more office workers.

There are also disadvantages, and significant ones.

• Instability since Junior programmers earn much less than Senior programmers, because they have little experience, and the employer cannot trust them with important orders.
• A responsibility, which falls on your shoulders, because the performance of the project and the success of the company will depend on you. If you're a freelancer and don't take it too seriously, you may never find the job you want.
• Difficulty finding a suitable position, if you are without any experience. Moreover, this applies to freelancers, for whom the search for the first orders is a real challenge.

Previously, most of the programmers underwent independent training on Internet resources, but now the employer is increasingly paying attention to the availability of relevant documents: theses, diplomas, licenses, certificates. At the very beginning of your journey, you should decide on the education: higher or secondary. It is noted that there is not much difference. Then we choose the direction that you like and in which it is convenient for you to work. We pass exams and go to further education (university, university, and so on).

If you have dreamed of staying at home and making money since childhood, then freelancing (remote work) would be an ideal option. Now it is enough to go to a special website, take a suitable course and then pick up your diploma, which will have a significant impact on the interview. However, the courses provide only superficial knowledge, so in the process of work you have to finish your studies.

Today there are many online courses that can teach you how to program from scratch.

• Skillbox. The main advantages of the course are the free training schedule, as well as professional teachers who have all the necessary licenses. The training takes place rather quickly (in comparison with real institutions) - about four months. After the learning process, you will write your thesis - a program that will become a mini-analogue of the popular Telegram messenger.
• GeekBrains. This is a fairly popular resource for teaching programming in general, as well as individual languages ​​(Java, Python, PHP, C #, and so on). Free training schedule, many free and paid courses that will be of interest to a person of absolutely any age and, of course, professional teachers.
• Hexlet. Another good site, which is the development of domestic programmers. Here they teach working with languages ​​such as Ruby, PHP, Java, working with databases, website layout, and more.

Choosing the profession of a programmer, you should definitely remember that a programmer is to some extent a scientist who must know an incredible amount, be able to use the Internet, computers and other tools.

The programmer must have such qualities as:

• ability to self-study;
• well-developed thinking;
• teamwork skills (useful even if you are a freelancer);
• initiative;
• a responsibility;
• attentiveness;
• concentration;
• good memory.

These are just the basic qualities that absolutely every programmer should have. Also, a programmer should have in his arsenal an incredible amount of skills, it must be developed both technically and humanitarian. The main skill of a programmer is Knowledge of foreign languages. Knowledge of English is a prerequisite when applying for a job in an office, since you will need to read the documentation (and not the fact that it will be written in Russian), as well as be able to communicate with other programmers on business trips and other trips.

If you go deeper, then all programmers are divided into several levels according to their knowledge and skills. Let's take a look at the career path of a Java programmer.

• Java Junior Developer. This level is the beginning of your career: there will not be much demand from you, there is not much work, but the payment will be appropriate. At this level, you need to know databases, OOP and the Java programming language itself with all its basics (syntax, multithreading, compilation features, standard libraries).
• Java Developer. This level is a little more serious than the previous one: responsibility is getting higher, but there is still not much work to do. The following requirements are imposed on this position: knowledge of one foreign language at a technical level, work experience of more than 1 year, proficiency in SEP, knowledge of databases, DBMS, operating system devices, server technologies, and the like.
• Java Senior Developer. From that moment on, you are a personally responsible developer with a successful career. At this stage, you are given a lot of practice, and the salary increases significantly, as well as the requirements for you.

There are three ways of further development of events.

• Office work (in Russia). This option is chosen by about 35-38% of future programmers. In principle, there is nothing special here: every morning you go to the office, work there until 8 pm and come home tired.
• Work abroad. This option is already more in demand and popular, because salaries in Europe and Asia are much higher than in Russia. There programmers are especially in demand. For example, in China, for example, there is a constant shortage of personnel, while mechanical engineering and computer technologies are quite well developed there.
• Freelance (remote work). But this is already the most interesting way, because of which this profession is often chosen. It's so nice: get up when you want to, go to bed at any time and have a free, independent work schedule. But here, too, there are some nuances. For example, a free schedule can simply "kill" your motivation, since many people relax a lot in a non-work environment at home, and it is much more difficult to concentrate on a task under such conditions.
