joosa+ *.java jasmin *.j java Main < in1 > out1 Main will start a game of Pong. The input is described by the program and hopefully self explanatory. If you don't find infinite loops funny don't try another wall then the stone wall. We had those others walls working (with modified slopes) but somehow it broke at the end. Anyways, if you play Pong with the stone wall it should work fine. Have fun!
