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.
