What is the barrier to entry into the profession today?

Question

IT education

Good day. Now I'm trying to catch up, to become part of the IT community. Behind a couple of years of official experience as a system administrator and about 10 years of varying success in experiments with a Linux home server. There is a desire to get a job as a Java programmer (I understand that it sounds too general). So, the question is: does it make sense to study only the language, or no one needs it now, and should one choose and study a certain stack of technologies?

Answer 1

Learn OOP and data structures in Java, then move on to the stack and practice. One language, of course, is far from enough. Employers are interested in practice, the ability to use development tools, write tests, etc.

Answer 2

Essentially, Java is a tool for creating things to solve problems. The customer needs software that solves any issues. Sometimes the customer does not care what it is written on. At least in php, as long as it works.
It is necessary to study where there are more customers. Make websites - php, html, css and more.
Write software - any convenient language in which you can write software that is interesting to customers without crutches.

Answer 3

I wonder how you will learn the java technology stack without knowing the language itself?
A language is the simplest thing in the stack of technologies and frameworks.
If you have experience as an administrator, it is possible for an intern to have an intensive course of 50-100 academic hours.
June needs more.
