Is it worth taking programming courses

More and more people want to get into the IT sphere. And not because they like programming and they have a predisposition to it, but from the opinion, inspired from all the cracks, that there is a lot of money in this area.

From here we can observe that more and more various programming courses appear, the teachers of which assure that in the shortest possible time they will teach programming a popular language, for example, JavaScript, PHP, Python, or use some newfangled framework, and contribute to employment in a high-paying job in a large company. On the websites of various courses, many pseudo examples of successful employment and salaries of students who have taken courses are brought up. However, not everything is as smooth as it might seem to many.

Cons of programming courses

  • Teach languages ​​or tools, but not programming
  • Rarely provide educational knowledge that can be reapplied
  • Provide only the basics of programming
  • The courses are very expensive
  • Will not give real hands-on experience that can only be obtained on a real project
  • A certificate or diploma does not provide employment benefits

Advantages of programming courses

  • Provide starting material on a programming language or development tool
  • A little practice in a simple code
  • Training under the supervision of a teacher
  • Independent problem solving
  • Help improve skills, consolidate existing knowledge or remember forgotten

I completed the course and will start earning a lot

Most who now come to the IT industry and take courses are looking for quick and easy money. At the same time, they are ready to throw money on dubious programming courses, in the hope of how quickly they can learn to program and make big money.

They will not start making money. Nobody will pay money just for the fact that you have learned something there. After all, the main thing is to solve specific tasks, to understand what you know and how to apply this knowledge. No one needs imitation of actions, but a result.

Completed the course and became a professional programmer

No professional teacher and the best training courses can teach programming if a person does not want to. After all, the main thing here is hard training and painstaking work on oneself. Moreover, in one course and even in ten, twenty, one hundred courses it is impossible to study and apply everything in practice. Programming courses will not teach you to think with your head until you do it yourself. There is nothing in the courses that you cannot go through and study yourself. There is the same information that can be found in open sources, official documentation and books. As a result, completing the course is a simple waste of money and rarely will remain in your memory after taking it.

Received a certificate with a diploma and will be torn off with hands

Any paper that you will be given after completing programming courses, whether it be a sealed diploma or a signed certificate, is just an ordinary piece of paper and nothing more. You don’t need to think that with a bunch of certificates you will be immediately torn off with your hands at any job. There is only one value – your knowledge. Whether you have at least ten certificates in different areas of programming, until you prove your professionalism and knowledge in practice, no one will care about you. Courses cannot guarantee to be accepted for a good job in a large company, but only give you some knowledge that you should already use when looking for a job.

Chose a cool advanced course

If you decide to take courses in programming, then choose the level for which your knowledge is designed. There is no need to think that by choosing the highest, most difficult and expensive course you will immediately become a professional. If you do not have basic knowledge in programming, or in a specific technology, then it is better to choose a course for beginners and learn programming from the very beginning.

Completed the course, but no portfolio

If, after completing the courses, you could not build up a portfolio, then we can assume that such programming courses were wasted. After all, if this was not just a course of theoretical knowledge, but practical work was carried out and assignments were completed, then a portfolio is simply necessary. When employed without work experience, it will be an excellent indicator of your real knowledge.

But it is worth understanding that these pros and cons will directly depend on the programming courses you want to take.

How to Get the First Java Developer Job

junior java developer job

Once you have sent java junior developer resume, and received an invitation for an interview, you need to understand what kind of knowledge you need to successfully pass the interview and get your first job. To be java developer a knowledge of Java is not enough. This is only 10% of what you need to know, and now we will deal with the remaining 90%.

We have gathered widespread the IDE, frameworks, some “chips” of the PLO as a whole, as well as reinforced all useful material in the form of links. However, if you find an article incomplete, be sure to share your feedback in the comments to it: this information will help those who began their path of development in the field of coding in Java.

Basic theoretical knowledge

java languageEverything starts with the PLO. It is the alpha and omega of all the issues that affect object-oriented programming languages. Prepare and banal questions from the category of “3 (or even 4) the principle of the PLO” and to task more difficult, for example, explain what is happening in the code written on a hypothetical programming language.

Often heard questions about OOP principles, access modifiers, collections, etc. But the fun only starts when you go directly to the PL.

Java is replete with libraries that provide more flexibility, but you can stumble and Java Core. Here are just a few of the issues on the language:

  1. What happens if you override equals () does not override hashCode ()?
  2. Why clone method is declared as protected?
  3. What is the difference between the final, finally and finalize ()? Tell us what it is.
  4. What happens if the only constructor will be declared as final?
  5. Tell us about all the methods of the Object class.
  6. What is the difference between equals () and ==?
  7. Abstract classes and interfaces: is there a difference?
  8. When is it better to use an ArrayList, and when – LinkedList?

And so on to infinity. To become a junior java developer, Java Core should be well aware of. But when you understand all the subtleties of the language, we can safely proceed to the study of frameworks.

English language

It is necessary. If you have very bad – sign up for courses. If everything is fine, but it would be better – British serials with subtitles to help.

Do not think that it is necessary only for the ability to read something like «toString» or «valueOf». Documentation, various problems whose solutions have long been waiting for you on Stack Overflow, helpful English-language materials – it’s really handy.

But the employer primarily wants, so you can freely communicate with foreign colleagues. In general, even if your dream job is in Germany, before learning how to «Deutsch zu sprechen», get your hands on the English: it is one of the pillars of the IT-sphere, without which you will not become java developer.

IDE

IntelliJ IDEA – everyone’s favorite, comfortable, “lamp” development environment. But very harmful, especially for a novice programmer. Accustomed to the “light” code in IntelliJ IDEA, you can always hate NetBeans and Eclipse (and experience with the latest IDE requires no means rare).

We started with IntelliJ? Well, try to “break the fingers” under Eclipse: it is a rewarding experience for both the user given the IDE, and for the programmer in general. But in general, perfect if you master all 3 IDE: resume and extend the useful life. Parallel to learn hotkeys, with which writing / testing and debugging code will be accelerated.

Operating system

Docker appeared, and somehow at once it became easier, but the knowledge of MacOS and / or Ubuntu is still the priority, if you want to become junior java developer. Work with them easier and more enjoyable due to the native console with the appropriate teams. Is it worth noting that not all of the Windows often fly, and free operating system – all at a premium (not, pirates do not use in companies, either litsenzionka or free running)?

If you look at the horror of programmers work with the console and magnify them true professionals, try to reach their level. Just install the appropriate OS and use: knowledge and skills will come with time itself.

Database

The vast majority of companies focuses on the knowledge of MySQL – the universal tool for working with databases. But knowledge – does not mean a one-day experience, or “Yes, I’m with it once faced.” You have to really understand the needs and to be able to optimize the structure. Complicated? Start just to be able to install the database and study of the CRUD (create, read, update, delete).

Sometimes it may require knowledge of PostgreSQL, MongoDB, SQLite, Redis, etc.

HTML, XML, JSON

programming java codeHTML will be a good helper to work with servlets, GUI and more. Java is still used on the Web, in complex architectures, where the stability of the override. However, it no longer refers to the server-side. Still, knowledge of hypertext markup language plus will not be exact. Read more about HTML, you can check out here And more useful material for its study will find in this article.

XML data format – the eternal companion and parsing log files. Ability to work with XML is not critical, unless otherwise stated in the requirements, but it will show you as a programmer with the best hand.

But JSON stands for JavaScript Object Notation. Unlike the XML, is a compact text format data exchange and is designed for easy perception of the person. Often used in the exchange of information between the server and a web browser. The Internet abounds with materials about JSON, so you quickly understand how to work with them.

Frameworks

Spring MVC – the leader of the modern rating. To become junior java developer most companies require knowledge of the framework. The main reason – its universality. Roughly speaking, it is a set of frameworks that allow you to perform various tasks.

The JSF all a little different, and its main feature in conjunction with the components. Oracle has a support, a lot of additional tools, a friendly community and “human” documentation.

Vaadin is also focused on web development. Its main advantage is to work without the need to tie optional web-languages ​​such as JS, XML, HTML. It is well implemented MVP and MVC. The vacancy is less common these frameworks, but sometimes required.

The ability to read other people’s code

Yes, to be java developer, you need to think like java developer.

This work is often in a team, and this skill, like reading someone else’s code, be sure to take into account. If this experience is – use it in the resume and tell me about it in the interview. Otherwise, try to discover the Open Source and get involved in team development. Ability to work with someone else’s code is no less important than the knowledge of the language itself: it will show that you are good not only in his own style, but it can “adapt” to the other.

Employment Tips

  • Be sociable. Acquiring communication skills and expanding circle of friends, you accumulate valuable contacts and new knowledge. Actively participate in the interviews, not confined to himself after a “failure”.
  • Remember that the resume is your face, without which it is impossible to find a good job. To create a professional resume use it resume writing service https://resumesbot.com/it-resume-writing-service/ – these guys will help you write a resume that will competently emphasize your strengths.
  • Not to stay in one place. Change your job if the company’s current increase does not even shine. . This is true for all incl for beginners who are afraid of losing their first job:. Always best to move forward.
  • Keep learning. Discovering new industries, technologies and frameworks, you give yourself a lot of opportunities to break on.
  • Learn to sell yourself. When it comes to scoring the desired wages, many banal shy, even if it deprives the tightness half of what they could get. Sensibly evaluate their strength and not afraid to express the desired level of salary to the employer.
  • Attend seminars, Hackathon, and other activities aimed at honing skills.
  • Read a book, use the services and solve puzzles (you can just answer questions Stack Overflow).
  • Prefer currency working for foreign companies. You can generally move to another country if speak English well, and your skills match the stated in the vacancy.
