I am using windows 8, 64 bit.
I am learning GUI in Java. Generally I use eclipse IDE. I have also installed Net-beans.
I am trying to do a simple GUI program which will add two number and show their result. But the problem is that when I am running the program from IDE it is looking like this. 
. But when I am running this same class file from command line it is showing correctly. I have test the same code in both eclipse and Net-beans. But the result is same.
Source code for first picture.
import javax.swing.JOptionPane; // program uses JOptionPane
public class Addition
{
public static void main( String[] args )
{
// obtain user input from JOptionPane input dialogs
String firstNumber =
JOptionPane.showInputDialog( "Enter first integer" );
String secondNumber =
JOptionPane.showInputDialog( "Enter second integer" );
// convert String inputs to int values for use in a calculation
int number1 = Integer.parseInt( firstNumber );
int number2 = Integer.parseInt( secondNumber );
int sum = number1 + number2; // add numbers
// display result in a JOptionPane message dialog
JOptionPane.showMessageDialog( null, "The sum is " + sum,
"Sum Integers", JOptionPane.PLAIN_MESSAGE );
} // end method main
} // end class Addition
then I have made another simple program by window-builder which will perform the four arithmetic operattion between two number. But the result is same for this case. Another picture has added named picture two. source code for second picture.

it is not appearing correctly in IDE, but when the class file is running in command line, it is appearing correctly.
I have updated my JDK.
what may the cause and solution?
