Use abstract classes and methods: Java Essential Training: Objects and APIs

When designing an object-oriented, contract-based programming architecture, you can frequently choose between using interfaces and abstract classes. An abstract class is abstract because you add the abstract keyword, and then it can contain a mixture of fully implemented methods and abstract methods. Because it’s abstract, you can’t instantiate directly—you have to use one of its subclasses.
