This example differs from Diffing a working copy against a repository example only in the the right-hand revision parameter passed to an SVNDiffClient:

   1             /*
   2              * This corresponds to 'svn diff -rBASE'.
   3              */
   4             diffClient.doDiff(wcRoot, SVNRevision.UNDEFINED, SVNRevision.WORKING, SVNRevision.BASE,
   5                     SVNDepth.INFINITY, true, System.out, null);

This doDiff() call is equivalent to 'svn diff -rBASE' in the root of the working copy.

When you run the program you will see an output as follows:
