An Easy Java Program

Cut and paste the following into Ready to Program.

//name: A. Grate Programme
//date: Sept 15
//purpose: a starting program, shows output

public class Starter
{
   public static void main (String args [])
   {
      new Starter ();
   }

   public Starter ()
   {
      System.out.println ("Hello World!");
   }
}

Hit the "Run" button.

A window should appear that has the words "Hello World" in it.

Here is an explanation of the parts of the program:

class	A class goes around methods. They hold all of the code in a program.
Starter	This is the name of your program. You must save your file as "Starter.java"
public static void main (String args [])	This is a method. Methods go inside classes. They hold the instructions to the computer.
System.out.println ("Hello World");	This is how you print a message on the computer screen. You put what you want printed in quotes.
