Usually commonality will be expressed in the members of the superclass.

Even when a superclass method is appropriate for a subclass, that subclass often needs a customized version of the method.

Objects of all classes that extend a common superclass can be treated as objects of that superclass.

The subclass can redefine the superclass method with an appropriate implementation.

A subclass is not allowed to inherit methods that it does not need or should not have.

While has-a represents composition, is-a represents inheritance.

In Java, the indirect superclass is any class above the direct superclass in the class hierarchy.

Every class in Java directly or indirectly inherits from (i.e. extends) object.

Inheritance is sometimes also referred to as specialization because the subclass exhibits the behaviors of its superclass and can add behaviors that are specific to the subclass.

For a superclass and a subclass, the constructors and static methods or fields will be inherited.

For a superclass and a subclass, the objects of your class will receive all of the state (fields) and behavior (methods) of the parent class.

An indirect superclass is any class above the direct superclass in the class hierarchy.
