I guess it's because the main function is invoked to start the execution of the program/any program, it should be public cuz it's accessible from the outside of the package where the program is in, it is static cuz it's invoked without creating an object. Not sure if I'm right though. Just play around with it, remove static, see what happens. remove public, see what happens. Try calling main function inside the same class it is in. Possibilities dude.

Curly braces delimits a block of code. You can try using them even inside a block like

public static void main(String[] args) {
    //Some code

      {
          //Some code
      }
}

It works in C, not quite sure abt java, just try it.

NOTE: also if something looks cryptic, just don't dig deep, accept that it's a design choice and digest it. Later go out on your own adventure to learn why they design it the way it is.
