Whats the difference between "public static void main()" and 'public static void main(String [ ] args)"??

Question

Im a beginner

Answer 1

String [] args is the command line arguments part.
When command line arguments are passed then those are stored in that string args [] array

Answer 2

In the first case, you don't really care about the arguments being passed to your program. In the second case, they are stored in args.
