What’s the Output?

a. Determine the output of the following code:

   public class Point   {        int x, y;        public Point ()        {             x = y = 0;        }        public Point(int a, int b)        {             x = a;             y = b;        }        public boolean equals(Point p) // tests whether or not two Points are equal        {             return ( p.x == x && p.y == y);        }   }

   public class Example   {        public static void main(String[] args)        {             Point a;             Point b;             a = new Point(3, 4);             b = new Point (3, 4);             System.out.println(a.equals(b));        }   }

b. Determine the output of the following code:

   public class A   {        public void X()        {             System. out. println("Class A; method X");        }        public static void Y()        {             System.out.println("class A; method Y");        }   }

   public class B extends A   {        public void X()        {             System.out.println("class B; method X");        }        public static void Y()        {             System.out.println("class B; method Y");        }   }

   public class MethodCalls   {        public static void main(String[] args)        {             A a = new B();             a.X();             a. Y();             B b = new B();             b. X();             b.Y();        }  }
