Object References

•Object reference describes the location of an object

•The new operator returns a reference to a new object

Rectangle box = new Rectangle();

•Multiple object variables can refer to the same object

Rectangle box = new Rectangle(5, 10, 20, 30);

Rectangle box2 = box;

box2.translate(15, 25);
