Running a program from the command line and as applets

Explore sample programs at

Start Java, enter, compile and run a program. Step-by-step instructions appear at http://java.sun.com/docs/books/tutorial/getStarted/cupojava/win32.html.

Use Crimson Editor to enter your code (replace my name with yours):

	public class Hello
// program which prints "Hello World!"
// written by Wayne Summers

{
	public static void main(String[] args)
	{
		System.out.println("Hello World!");
	}
}

save your program as Hello.java
go to the command line and compile the program, by typing javac Hello.java (this creates a file called Hello.class)
on the command line, run your program, by typing java Hello
upload your program (Hello.java) to the assignment box in WebCT for this lab class.
