FIND THE DIFFERENCES BETWEEN CODE VERSIONS

Sometimes you want to know what's changed between two versions of your
code. If you've been diligent about keeping a change log or keeping
comments in your source control system, then you're on the right track to
find those differences. But even the most earnest developer can forget to
document a change once in a while.

JDiff is a tool that will report the differences between two versions of
your source code in the Javadoc format. You can run JDiff against each
version of source code that you want to compare. Each run creates an XML
file describing the source code. Then you can run JDiff against the two
XML files you just created. In this instance, JDiff creates an HTML file
showing you the difference between the two versions.

JDiff is implemented as a doclet, so you run it using the Javadoc tool.
The output of JDiff looks exactly like the Javadoc you're used to 
seeing
with a complete list of changes by package, class, method, etc.

When you need to see the difference between versions, you can use JDiff
to simplify the process.
