IBM have their own Java implementation - they have their own JVM and JDK.

In practice, when we're talking about Microsoft Windows, almost the whole world uses the Sun JVM and JDK. I wouldn't use the IBM JDK on a Windows machine unless I absolutely have to.

Besides IBM, there are also other vendors that have their own JVM implementations. BEA has a JVM (JRockit) for Intel machines that's supposed to be faster than Sun's JVM. HP have their own JVM for their Unix and OpenVMS servers. IBM have their own JVM for AIX and other platforms (besides the Windows version).

IBM's JDKs have traditionally been of good quality, sometimes edging out Sun's in certain benchmarks, especially server throughput (combined I/O and threading) benchmarks like the VolanoMark. That said, they have a smallish market share excepting on AIX, of course.

There was a time when IBM tools like VisualAge required or used IBM JVMs. I think the VAJ version we used to use had some hot swapping and debugging features that were not in the Sun JVM. I haven't heard much about the relative merits of Sun and IBM JVMs for quite a while.
