Problem with applets!!

I am a newbie to eclipse and java. I wrote a programme but when tried to run it, eclipse compiler generated an error : "Editor does not have an applet. Please help me out!!!

Code:

---

import java.io.IOException;
import javax.swing.JApplet;


public class mohsin extends JApplet{
        public static int a,b,c,o;
       
        public void main(String[] args) throws IOException {
                System.out.println("Enter an operator code to continue:");
                System.out.println("\n1 for addition.\n2 for subtraction.");
                System.out.println("\n3 for division.\n4 for multiplication");
                o = System.in.read();
                mohsin.option(o);
        }

public static int addition (int a,int b) {
        c = a + b;
        return c;
}

public static int subtraction (int a,int b) {
        c = a - b;
        return c;
}

public static int division (int a, int b) {
        c = a / b;
        return c;
}

public static int multiplication (int a, int b) {
        c = a * b;
        return c;
}

public static int option (int o) {
        switch(o)
        {
        case 1:
                mohsin.addition(a, b);
                break;
        case 2:
                mohsin.subtraction(a, b);
                break;
        case 3:
                mohsin.multiplication(a, b);
                break;
        case 4:
                mohsin.division(a, b);
                break;
        default:
                System.err.println("Wrong number entered, try again: ");
        }
        return c;
}
}

If you're trying to run this as an applet, you're doing it all wrong. In fact your code is not GUI code at all, but rather a simple console program.

First and foremost, decide what you want: a simple console program or an applet GUI. If the latter, then you'll need to read an applet tutorial as it will help you to understand what you need (such as an init method).

I just want to run the programme, whether simple or applet. I was forced to do applet by the compiler because when i clicked run, instead of running, it gives me option to run in either java application or applet. Please tell me how can i run this programme in simple

Remove the "extends JApplet" which will make it a simple console program.
