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, however, programmers in this area receive good money. Consider how to become a Java programmer, and what skills and knowledge are required for this.

Speaking about a programming language such as Java, remember that it is one of the oldest and most complex, but at the same time multifunctional programming languages. Cross-platform Java 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 capabilities end where the imagination of a programmer who writes in this programming language runs out. Java is a great tool, because the 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 is not worth doing. The first is mainly used for writing applications on Android, and the second is intended for front-end development of sites and web applications.

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

• personal contact with the customer and his 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, which we will now consider.

Advantages:

• high salary: from 70 to 120 thousand rubles;
• a huge number of jobs (demand);
• chic conditions in the office: free meals, a powerful personal computer, insurance, a convenient 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.
• Responsibility, which falls on your shoulders, because the operability of the project and the success of the company will depend on you. If you are a freelancer and take this not too seriously, then you may not find the desired job.
• The difficulty of finding a suitable position, if you are without any experience. This is especially true of freelancers, for whom the search for first orders is a real test.

Previously, most 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. Next, we choose the direction that you like and in which you are comfortable working. We pass exams and go to further studies (university, university, and so on).

If you have been dreaming of sitting at home and earning money since childhood, then freelance (remote work) will be an ideal option. Now it’s enough to go to a special site, take a suitable course and then pick up your diploma, which will have a significant impact on the interview. However, courses provide only superficial knowledge, so in the process of work you have to retrain.

Today there are many online courses that can teach programming from scratch.

• Skillbox The main advantages of the course are a free training schedule, as well as professional teachers who have all the necessary licenses. Training takes place quite quickly (compared with real institutions) - about four months. After the training process, you will write a 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 for individual languages ​​(Java, Python, PHP, C # and so on). A free training schedule, many free and paid courses that will be interesting 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 how to work with languages ​​such as Ruby, PHP, Java, work with databases, website layout and more.

When choosing the profession of a programmer, it is imperative to remember that a programmer is to some extent a scientist who must know incredibly much, be able to use the Internet, a computer, and other tools.

A programmer should have such qualities as:

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

These are just the basic qualities that absolutely every programmer should have. Also, the programmer must have in his arsenal an incredible amount of skills, it must be developed both technically and humanitarianly. The main skill of the programmer is Knowledge of foreign languages. Knowledge of English is a prerequisite for hiring an office, as 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 further, all programmers are divided into several levels according to their knowledge and skills. Consider the career path of a Java programmer.

• Java Junior Developer. This level is the beginning of your career: here they won’t demand anything special from you, there’s not much work to be done, but the payment is due. At this level, you need to know the databases, OOP, and the Java programming language itself with all its fundamentals (syntax, multithreading, compilation features, standard libraries).
• Java Developer This level is a little more serious than the previous one: responsibility becomes higher, but there is still not much work. The following requirements are imposed on this position: knowledge of one foreign language at a technical level, working experience of more than 1 year, knowledge of SEP, knowledge of databases, DBMS, devices of operating systems, server technologies and the like.
• Java Senior Developer. From that moment on, you are a personally responsible developer whose career has been a success. At this stage, they give you a lot of practice, and wages increase significantly, as do the requirements for you.

There are three ways for further developments.

• Work in the office (in Russia). This option is chosen by approximately 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, there is a constant lack of personnel, and engineering and computer technologies are quite well developed there.
• Freelance (remote work). But this is already the most interesting way, because of which they often choose this profession. After all, it’s so nice: to get up whenever you want, go to bed at any time and have a free work schedule that does not depend on anyone. But here there are some nuances. For example, a free schedule can simply “kill” your motivation, since many people in a home inactive situation are very relaxed, and focusing on a task in such conditions is much more difficult.
