Objects and References:

Review of the normal case

Remember the general pattern of our previous example:

box1 = new Box(1, 2, 3);

box2 = new Box(8, 5, 7);box1 = box2;

System.out.println(box1 = = box2);

// prints true

// Does box1 reference the same

// object that box2 references?

System.out.println(box1.equals(box2));

// prints true

// Does box1 reference an object that has

// the same contents// as the object referenced by box2?

box1 box2
