      public static void main(String[] args) throws IOException
    {


            //set input stream

            BufferedReader stdin = new BufferedReader(new InputStreamReader(System.in));

            //get numbers from user input

            //asks user for 1st number, then converts it to an integer

            System.out.print("Enter first integer: ");

            int x = Integer.parseInt(stdin.readLine());

            //asks user for 2nd number, than converts it to an integer

            System.out.print("Enter second integer: ");

            int y = Integer.parseInt(stdin.readLine());


            //add x,y

            int sum = x + y;

        System.out.println("My First Applet Application");
    }
} 



Now save it with name->javac MyFirstApplet.java

This creates the class file

         MyFirstApplet.class
