When "compile on save" is disabled do I have to compile my projekt before it runs? And how does the compiling work then?

Question

I'm learning Java at the moment and I'm using NetBeans as an IDE. When "compile on save" is disabled do I have to compile my projekt before it runs? And how does the compiling work if "compile on save" is disabled? How does it work when enabled? Thanks for your help

Answer 1

I'm not sure on netbeans, but in eclipse it means you have to save first every time you want to run the project.
