A Java applet that compares 3 integers…

Here is the source code of Java applet I have written which compares 3 integer numbers and outputs the biggest and the smallest number….I wont explain the code…

 

import javax.swing.*;
import java.awt.Graphics;

    public class ComparisionApplet extends JApplet{

           String result;
           String result1;

                   public void init()
                          {

                    int number1;
                    int number2;
                    int number3;

                    String numbera;
                    String numberb;
                    String numberc;

                    numbera = JOptionPane.showInputDialog("Enter first integer:");
                    numberb = JOptionPane.showInputDialog("Enter second integer:");
                    numberc = JOptionPane.showInputDialog("Enter third integer:");

                    number1 = Integer.parseInt(numbera);
                    number2 = Integer.parseInt(numberb);
                    number3 = Integer.parseInt(numberc);

                    if(number1 > number2)
                    if(number1 > number3)
                         {
                         result = number1 + " is the biggest number";
                     }

                    if(number2 > number1)
                    if(number2 > number3)
                       {

                         result = number2 + " is the biggest number";
                     }

                    if(number3 > number1)
                    if(number3 > number2)
                         {

                         result = number3 + " is the biggest number";
                      }

                    if(number1 < number2)
                    if(number1 < number3)
                       {

                        result1 = number1 + " is the smallest number";

                       }

                    if(number2 < number1)
                    if(number2 < number3)
                        {

                         result1 = number2 + " is the smallest number";
                         }

                    if(number3 < number1)
                    if(number3 < number2)
                     {

                       result1 = number3 + " is the smallest number";
                    }

        }

            public void paint(Graphics g)
                    {

               super.paint(g);

                    g.drawString(result,25,70);
                    g.drawString(result1,25,100);

                }

}
