Generics allow compile-time type checking without having to create many container classes, each containing almost identical code. This is achieved by compiling the Java language code to an intermediate representation called , instead of directly to architecture-specific. Java can be easily extended since it is based on the Object model. It supports Java 6 and some Java 7 features, offering an implementation compatible with the standard library. Java remains a , controlled through the. Gosling, James; Joy, Bill; Steele, Guy; Bracha, Gilad.

Licensing and documentation Documentation [ ] Main article: Javadoc is a comprehensive documentation system, created by. A Java program may contain multiple classes that have main methods, which means that the VM needs to be explicitly told which class to launch from. Stand-alone programs must declare this method explicitly. Where prior implementations of these looks and feels may have been considered lacking, Swing in Java SE 6 addresses this problem by using more native drawing routines of the underlying platforms.
