Playing with semantic holes in Java's notions of equality

IntLongWat.java

public class IntLongWat {

  public static void main(String[] args) {	
	
    System.out.println(new Integer(1).equals(1)); // true	
    System.out.println(new Long(1).equals(1)); // false, it only equals 1L - so much for semantic equivalence
    System.out.println(new Integer(1).equals(new Long(1))); // false... Y U NO EQUAL?  
		
    // although
    System.out.println(new Integer(1) == 1); // true		
    System.out.println(new Long(1) == 1); // true... WAT? they are == but not equals() ?
    // so then, transitively...
    // System.out.println(new Integer(1) == new Long(1)); // COMPILE ERROR... CLEVER BASTARD
    Object oInt = new Integer(1);
    Object oLong = new Long(1);
    System.out.println(oInt == oLong); // false, of course - so much for transitivity
  }
