1. Implementing the Composite and Visitor Patterns in Java

Implementing design patterns can be difficult and little sample code exists that walks you through the process. The purpose of this article is to walk through the implementation of a program that uses the Composite and Visitor design patterns. The sample project is written in the object-oriented language, Java, but it could just as easily have been written in C++.

8. Java Abstraction (abstract)

Java supports marking a full class as abstract as well as class members. A subclass must either implement the abstract members or you must declare the subclass abstract (which delays the implementation to it's subclass).

10. Java Interfaces (Yes)

General Info: Interface

An element of coding where you define a common set of properties and methods for use with the design of two or more classes.

Both interfaces and abstract classes are types of abstraction. With interfaces, like abstract classes, you cannot provide any implementation. However, unlike abstract classes, interfaces are not based on inheritance. You can apply an Interface to any class in your class tree. In a real sense, interfaces are a technique for designing horizontally in a class hierarchy (as opposed to inheritance where you design vertically). Using interfaces in your class design allows your system to evolve without breaking existing code.
