Programming in Java for the First Time


We are going to type a simple program in notepad:

class HelloWorld {
    public static void main(String[] args) {
        System.out.println("Hello World!"); // Display the string.


Save this as in a directory on your h: drive


Now in the command prompt (Start-run-cmd)

Set the path to the compiler:


path c:\program files\java\jdk1.7.0_17\bin


Lets compile the program and then run it.
