Good point, Hisaji.  I've attached an example JTS program.  We'll add
examples to the src code in the next release.

Thank you very much for your great work, Mr. Davis.

 I've tried to create some programs by using JTS's jars.

 If possible, could you  show any simple sample java programs using JTS?

 Regards.
