A sub class has an 'is a' relationship with its superclass. This means that a sub class is a special kind of its super class. When we talk in terms of objects, a sub class object can also be treated as a super class object. And hence, we can assign the reference of a sub class object to a super class variable type. However, the reverse is not true. A reference of a super class object may not be assigned to a sub class variable. The following statements illustrate this concept by creating a Student object and assigning it to a Person variable. However, when we try to assign the reference of a Person object to a Student variable, we get a compilation error.
