Convert to Applet

How would I convert my program into a working applet? I just cant figure it out?
It takes 10 grades input by a user then finds the average, number above average, and the number below average.

Code:

---

package AverageTestScore;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;

public class AverageTestScore extends Applet
{
        static BufferedReader stdin = new BufferedReader
    (new InputStreamReader (System.in));
    static InputStreamReader converter = new InputStreamReader (System.in);

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

                double[ ] grade = new double[10]; // assume no more than 70 grades
        int gradeCount = 0;
        double sum = 0;

        page.drawstring("Enter Grade: ");

                double value = Double.parseDouble(stdin.readLine());

                while(gradeCount < 10 && (value >= 0 && value <= 100)){
          grade[gradeCount] = value;
              sum += grade[gradeCount];
          gradeCount++;
          System.out.print("Enter the next grade (Negative to skip to averages): ");
          value = Double.parseDouble(stdin.readLine());
  }


  if(gradeCount == 0)
      System.out.println("No valid grades were entered");
  else{
      double average = sum / gradeCount;
      int count = 0;

      for(int k = 0; k < gradeCount; k++)
          if(grade[k] > average)
                count++;

      System.out.println("The average is: " + average);
      System.out.println("The number of grades above average is: " + count);
      System.out.println("The number of grades below the average is: " + (9-count));
  }
    }
    }

Hi,
First of all you have to do your initialization process in applet's init() function, not main().
I recommend you to search for some resources and learn applet life-cycle basics.
