//try this code, u will get a basic idea
import javax.swing.JOptionPane;

public class Addition {

public static void main( String args[] )
{
String firstNumber; // first string entered by user
String secondNumber; // second string entered by user
int number1;
int number2;
int sum;

// read in first number from user as a string
firstNumber =
JOptionPane.showInputDialog( "Enter first integer" );

// read in second number from user as a string
secondNumber =
JOptionPane.showInputDialog( "Enter second integer" );

// convert numbers from type String to type int
number1 = Integer.parseInt( firstNumber );
number2 = Integer.parseInt( secondNumber );

sum = number1 + number2;

JOptionPane.showMessageDialog(
null, "The sum is " + sum, "Results",
JOptionPane.PLAIN_MESSAGE );
System.exit( 0 );
}
}
