Public static void main(String ...hello){}

Question

above method. whats is the that "..." , what they doing ?

Answer 1

Looks like an array notation from some languages. It just the same as
main (String[] hello) {}

Answer 2

Pseudo code:
// array notation
var a = func (["arg1", "arg2", "arg3"]);
// triple dot notation
var a = func ("arg1", "arg2", "arg3");

Answer 3

If you use array notation [] you must give an array as argument for function call, when using triple dot notation (probably) you can pass separeted arguments, that will be used to craft an array
