Here's the sample Java application that I'll develop through to the compiling and running stages over the next few sections. Place this code in a file named ch10_01.java:

public class ch10_01 
{
    public static void main(String[] args)
    {
        System.out.println("Welcome to Java");

C:\>java ch10_01 
Welcome to Java

As you can see, this is not the most powerful of programs, but it's simple enough to get us started. We'll work up from this point to windowed Java applications at the end of the chapter. To see what's going on in ch10_01.java, I'm going ...
