The Java Debug Interface (JDI) is a high level Java API providing information useful for debuggers and similar systems needing access to the running state of a (usually remote) virtual machine. It provides information useful for debuggers and similar systems needing access to the running state of a (usually remote) virtual machine.

The JDI provides introspective access to a running virtual machine's state, Class, Array, Interface, and primitive types, and instances of those types.

The JDI also provides explicit control over a virtual machine's execution. The ability to suspend and resume threads, and to set breakpoints, watchpoints, ... Notification of exceptions, class loading, thread creation... The ability to inspect a suspended thread's state, local variables, stack backtrace...

JDI is the highest-layer of the Java Platform Debugger Architecture (JPDA). For more information on the Java Platform Debugger Architecture, see the Java Platform Debugger Architecture documentation for this release and the Java Platform Debugger Architecture website.
