Mini Java Collection 4

Sean O'Connor

Impromptu Java source code for fun. 1/ Mini game engine and example game. Being small it should be easy to learn. 2/ Learn text using a hashtable based symbolic if-except-if tree structure. 3/ How to reliably obtain sample pictures from the internet using Java. 4/ Zobrist random number generator, intended as a replacement for the assembly language RDRAND instruction which cannot be directly accessed by Java.
