IFFERS FROM THE

After the last chapter, which was one of the longest in the topic, this chapter
should come as something of a relief. It is one of the shortest in the topic. Why?
Because the IBM Java Software Development Kit is practically identical in use
to the Sun package. It differs in only a few respects and that is all we will talk
about here.
One of the biggest differences is the version of Java available from each
vendor. Sun has the newest versions, as they have been defining what those are.
IBM is still releasing the 1.3 versions of Java as Sun begins to release 5.0. But
you may not want or need the “bleeding edge” of the technology.
