Hi Friend,

Try the following code:

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

public class Calculate{
public static void main(String[] args)
{
String input1 = JOptionPane.showInputDialog("Input First Number");
int num1=Integer.parseInt(input1);
String input2 = JOptionPane.showInputDialog("Input second Number");
int num2=Integer.parseInt(input2);
int sum=num1+num2;
int diff=num1-num2;
int mul=num1*num2;
int quo=num1/num2;
JOptionPane.showMessageDialog(null,"Addition of numbers is: "+sum);
JOptionPane.showMessageDialog(null,"Difference of numbers is: "+diff);
JOptionPane.showMessageDialog(null,"Multiplication of numbers is: "+mul);
JOptionPane.showMessageDialog(null,"Quotient of numbers is: "+quo);
}
}

Thanks
