SOS SOS !!The Program Asks me the same number twice

Question

I am trying to do the exercise 5.11 from Java Deitel 4th edition it says
"Write an applet that reads five numbers, each between 1 and 30. For each number read, your program should draw a line containing that number of adjacent asterisks. For example, if your program reads the number 7, it should display *******."
This is my code:
// Java core packages
import java.awt.Graphics;
// java extension packages
import javax.swing.*;
public class Exe5_11 extends JApplet {
     public void paint( Graphics g )
int number;
String input;
     super.paint( g );
JTextArea outputTextArea = new JTextArea();
outputTextArea.setText("Hystograms\n\n");
     for ( int i = 1; i <= 5; i++ ) {
number = 0;
while ( number > 30 || number < 1) {
input = JOptionPane.showInputDialog("Enter Number " + i );
// convert user's input to an int
number = Integer.parseInt( input );
} // end while input
// display asterisks
for ( int j =1; j <= number; j++) {
outputTextArea.append ("*");
outputTextArea.append ("\n");
} // end for
JOptionPane.showMessageDialog( null, outputTextArea,"Hystograms", JOptionPane.INFORMATION_MESSAGE );
System.exit(0);
} // end paint method
} // end class Exe5_11
The problem:
The program asks me twice for the first number I don't know why? The logic is good, I think is something related with the scope of the variables or something particular with Java I don't know jet.
Please help me, I have spent 2 hours in this exercise.
THANK YOU IN ADVANTAGE!!
