IDE combines the editor, compiler and other useful tools in the same software package. Its advantage is that when a program with syntax errors is compiled, the programmer sees the error messages and the original program at the same time -- this makes debugging much easier. Also, some IDEs contain debuggers. Visual J++, VisualAge for C++ or Java, Java WorkShop, and Visual Caf�?�© are IDEs.

A Java IDE comes preloaded with or supports Java Development Kit and provides GUI interface to the Java execution environment. Java IDEs support multiple JDK versions and the users can switch the versions based on the requirement. Eclipse, JBuilder and CodeWarrior are examples of Java IDEs.
