this is a reserved word in Java. The reference to an object that is passed to any object's nonstatic method is called the this reference. Only nonstatic, instance methods have a this reference. For example, the two getEmpNum() methods for the Employee class perform identically. The first method simply uses the this reference without you being aware of it. The second method uses the this reference explicitly. Both methods return the empNum of the object used to call the method.
