Answer 1

To compile a java code you wrote, you have to use the javac command in terminal (or power shell in windows ) but he will not recognize the javac command unless you set up the path for the jdk. To do that go to :
-Control panel -> System -> Advanced System settings -> Environment Variables. There you will find the path variable. Click on it then click edit and write in there the path for the jdk bin folder (usually is C:\ Program files \ Java \ jdk (something) \ bin ). If you already have something written in the path variable just put a ; after that and then write the jdk path.
Then restart your computer and then powershell should recognize the jdk commands including javac
