There are plenty of design patterns floating around the programming world, and in time, a particular set of 23 of them has become accepted as the standard set. These patterns were first corralled in a book named Design Patterns: Elements of Reusable Object-Oriented Software (1995, Pearson Education, Inc. Publishing as Pearson Addison Wesley) by Erich Gamma, Richard Helm, Ralph Johnson, and John Vlissides — who have since been called the Gang of Four, or GoF, for short. And those 23 design patterns became known as the GoF design patterns.
You see all 23 of those standard patterns in this book, and some additional ones as well. I explain what each pattern does and when you should use the pattern. You also see a programming problem that the design pattern solves, implemented in code. In other words, every design pattern is put to work in easily understandable, runable code in this book.
In fact, some of the design patterns have already been put to work by the people who wrote the Java programming language. In such cases, I also discuss the part of Java that implements the design pattern already — such as closing windows in Swing or registering listeners with event-causing objects. Doing so gives you an immediate leg up with the design patterns covered — hey, you might find yourself saying: That looks familiar.
