In case you haven't figured it out yet, these are the basic steps in creating Java programs (and pretty much any other computer programs):

**The 14 Step Programming Process**
0) State the problem 1) Understand the problem 2) Find/Develop an algorithm that addresses the problem 3) Understand the algorithm 4) Translate algorithm into Java 5) Enter/Edit program in text editor 6) Attempt to compile program using javac 7) Look at the compiler output 8) If there are no syntax errors skip the next step 9) Fix bugs and redo step 5 10) Run the program using java 11) Look at the program output 12) If the output is correct skip the next step 13) Fix semantic errors and redo step 5 14) Start testing for more semantic errors.

You might say there is nothing constant in the field of computing except change. Assuming you were even born after 1984 you might not know that it was an interesting time. People were discussing breaking up IBM because it had the patent on the PC platform. With 640K on-board, it was a formidable machine. They were talking about IBM's "predatory market practices". Meanwhile IBM was talking about their ability to "Innovate".
