Can a LABEL block be used without loop?

Question

Can a LABEL block be used without loop? Any examples?

Answer 1

Here is an example of using labels and break statements without a loop:

        block1: {
            if (a < 0) {
                break block1;
            }
            if (b < 0) {
                break block1;
            }
            return a + b;
        }

Answer 2

  public static void main(String[] args)
  {
    hello: break hello;
  }
