During the past five years (1996-2001) four versions of Java have been released. The key features in each release are as follows: Java 1.0 — The first public release of Java contained 212 classes organized into 8 packages. Java 1.1 — The second release doubled the size of the Java platform to 504 classes organized into 23 packages. This release introduced the delegation event handling model and inner classes, leading to significant improvements in performance of the Java virtual machine. Java 1.2 — The third release tripled the size of Java to 1520 classes organized into 59 packages. This release is also called the Java 2 Platform. Java 1.3 — Minor updates to Java 1.2 release (e.g., includes support for Java Sound as part of the Java Platform). This release is also called the Java 2 Platform, version 1.3.
