    public static void main(String[] args) {
        new MyTestClass().myMethod();

Answer 1

public void stuff() {
  int i = 48;

  { 
    int i = 21;
    System.out.println(i); // prints 21
  }
  System.out.println(i); // prints 48
}

Basically, it's a way to create scopes smaller than entire function... Benefit?.. have the people stare at your code longer before they understand it... IMO it's bad style and should be avoided
