Java Quiz

public class Overload {
    public static void main(String args[]) {
        int result = foo(new B(), new B());

    public static int foo(A a, B b) { return 1; }
    public static int foo(B b, A a) throws Exception { return 2; }

    static class A { }
    static class B extends A { }

Without using a compiler (using the JLS and JLS report is allowed), answer the following:

  1. Does this code compile?
  2. If yes - what is the result from running the program?
  3. If no - why not? List all errors.

Answers on a postcard.
