Philip Johnson

The document discusses modern Java constructs introduced after Java 5, including collections, generics, autoboxing, enumerated types, annotations, and how to properly design classes to work with collections. It provides code examples and best practices for using these constructs and highlights resources like Java in a Nutshell and Effective Java for further reading.
