Every JDK provides an implementation of the basic, command line debugger “jdb” in its development tools package. You can also use an integrated development environment (IDE) for Java development and debugging, for example, Sun Java Studio, IBM WebSphere Studio, JBuilder, and Eclipse. In addition, there are standalone JPDA debuggers such as JSwat.
If you use an IDE or standalone debugger tool, consult the documentation provided by the vendor for specific JDK requirements.
The jdb debugger is not included in the JRE distribution.
To use jdb, you must install the JDK, which lets you access the
jdb debugger.
