Question

Java

Hello! I recently started learning Java programming, I practice in the IntelijIDEA program.
Tell me, please, what set of programs should be in order to create full-fledged programs and games?
From writing code to compiling into a finished program / game.
Thank you!

Answer 1

jdk + build system (maven/gradle) + knowledge of patterns + ide/text reactor to taste

Answer 2

In addition to the answer of anyd3v, I would also name a version control system (preferably git), a bug tracker (jira, etc.), a continuous integration system (jenkins). Plus debugging tools depending on what you write. Let's say if you write a REST service, then it's curl and tcpdump.

Answer 3

I recommend VisualVM.
