For readers who know Java and have written at least a few programs in it, and are particularly familiar with anonymous inner classes, software consultant Holub explains programming in an object-oriented way, and how to use design patterns to solve commonplace problems in object-oriented systems. He says his account augments rather than supplants the standard Design Patterns by Gamma, Helm, Johnson, and Vlissides, known as the Gang of Four. There is no bibliography.
