[DUPLICATE] public static void main(String[ ] args) in here what is args doing exactly?

Answer 1

You can pass arguments to your program if you start it via console/ide, see:
https://docs.oracle.com/javase/tutorial/essential/environment/cmdLineArgs.html
All arguments will be stored in the String array named args and you can access and handle them in your program.
