2.5. Anatomy of a Simple Java Program

Let's write the simplest possible Java program to begin. When run, this program will output the text string “Hello,” along with the value of the name variable to the command line.

2.5.1. Hello.java

/* file: Hello.java 
   purpose: print a simple string to the command line
   author: E Hewitt
   created date: 4.12.02
*/
package javaforcf;
// declare the name and visibility of this class
public class Hello {

// main method accepts an array of strings as arguments
public static void main (String [] args) {

// create a new String object with the value of 'Jeremy'
String name = new String("Jeremy");

// print the static text and the variable together
// out to the command line
System.out.println("Hello," + name);
        }
}
