Download hundreds of tools. The Java 2 SDK, from Sun Microsystems, puts unprecedented programming power into the hands of Java developers and gives enhanced functionality to end users. The new Java standard appears to be the richest ever, though end users may have to wait to reap all the benefits promised in this release. Swing The most visible improvement in Java 2 is its set of classes that lets programmers create highly graphical applications and applets.
