// Review: last time we wrote a "driver" for our Tic-Tac-Toe game.

// Running a Java program from the command-line (ex. a Linux terminal window):
// "javac" compiles the .java source file into a .class file, which is in bytecode language.
   javac TTTDriver.java
// then, you can "run" a class that has a main method: 
   java  ClassName    (without the .class extension)

java TTTDriver

// as you can see, we can write code in any editor, compile it, and run it
// from the command-line without DrJava!

// let's process arguments in TTTDriver (like who plays first)
java TTTDriver O
java TTTDriver X

// what's the problem here, and how did we "fix" it?
java TTTDriver F
java TTTDriver 55

// what do you think happens here?
java TTTDriver abc xyz

// we want the program to not run if the number of arguments is incorrect.

// now, let's write a text driver (no GUI):
java TTTTextDriver

// (watch out for IOExeptions when working with Input/Output!)

// we don't care about the list of args in the TextDriver:
java TTTTextDriver abc def xyz 555
