This trail is home to coverage of new APIs added to the most recent releases of the Java^TM 2 platform, version 1.4 and the new version 5.0.

Generics, introduced in J2SE 5.0, is the long-awaited enhancement to the type system. It allows a type or method to operate on objects of various types while providing compile-time type safety. It adds compile-time type safety to the Collections Framework and eliminates the drudgery of casting.

Full-Screen Exclusive Mode API teaches you about a powerful feature of J2SE^TM version 1.4 that allows the programmer to suspend the windowing system so that drawing can be done directly to the screen. Programmers writing games or other graphic-intensive applications should read this lesson.
