Triangle problem

How many triangles with sides of integer length have a sum of sides being a particular number?  This program calculates this for sum of sides up to the number specified.  It displays the result in raw form (listing all the possible triangles) or as tabulated totals of the number of triangles adding up to any particular sum.  The results are displayed in the Java Console.  There is a pattern to the results, but the pattern is not simple.

If you have any insights, workarounds or comments about this test page please contact Mickey Segal.  A listing of many Java resources is at this link.
