SECRET MESSAGE for file IO assignment. Please note that the first line contains a number indicating the number of remaining lines. I'll add a little twist to the assignment: it's up to you to decide if each line is encrypted separately or as part of the whole message (that is, is the previous character reset to (char) 32 for each new line). Please, if you figure it out early, don't give it away! sample java IO program

My paper on the experiences of teaching this course


Please come to the Sun lab to demonstrate your spynet programs at the time when our final is scheduled.

You still have to install jdk if you haven't already done so. The spynet assignment requires you to run a java application on your linux machine. "" is the official Java Linux site. You can download additional java-related material, including debug patches, Java 3D experimental ports, and the "JRE" development environment that resembles CodeWarrior.
