The procedure for this exercise will look different depending on the
Java development environment.  The following would be the steps using
Sun's JDK (version 1.0.x or 1.1.x) on Solaris or Windows, assuming
that the executables "java" and "javac" can be found in the execution
PATH variable:

* Using your favorite text editor, create a file named "HelloWorld.java"
  with the following contents:

	class HelloWorld {
	    public static void main(String[] args) {
		System.out.println("Hello, world");
	    }
	}

* Execute the following command from the directory where HelloWorld.java
  was created (a Windows-style command prompt is used as an example) to
  compile HelloWorld.java into the binary class file HelloWorld.class:

	C:\myprog> javac HelloWorld.java

  If you get any error messages, check HelloWorld.java for typos, and make
  sure that the JDK is installed properly.  If successful, you can list
  the contents of the current directory to see the HelloWorld.class file
  that the compiler generated.

* Execute the following command to run the HelloWorld program:

	C:\myprog> java HelloWorld

  The following output should appear:

	Hello, world
