Swing: JFormattedTextField ensemble de nombres que l'utilisation de l'edi Netbeans

J'ai un petit problème avec JFormattedTextField:
Je veux mettre le texte mis en forme les champs de numéros seulement. J'ai créé un avec Swing interface de NetBeans.

Mon code est comme suit:

package SerasApp;
import static java.lang.System.*;
import java.text.NumberFormat;
import java.text.ParseException;
import java.util.logging.Level;
import java.util.logging.Logger;
import javax.swing.JFormattedTextField;
import javax.swing.text.DefaultFormatterFactory;
import javax.swing.text.MaskFormatter;
import javax.swing.text.NumberFormatter;

}
//set position of label to be the center of the frame
public void PositionHiSera()
{
//find position of jpanel
int FrameHeight = this.Intro.getHeight();
int FrameWidth = this.Intro.getWidth();
int LabelSize[] = new int[2];
LabelSize[0] = HiSera.getWidth();
LabelSize[1] = HiSera.getHeight();
out.println(LabelSize[0]);
out.println(LabelSize[1]);
int Origin[] = new int[2];
Origin[1] = (FrameHeight/2)-(LabelSize[0]/2);
Origin[0] = (FrameWidth/2)-(LabelSize[1]/2);
//set label origin
HiSera.setLocation(Origin[1], Origin[0]);
}
public void HumidityLevel()
{
NumberFormat a = NumberFormat.getNumberInstance();
NumberFormatter b = new NumberFormatter(a);
DefaultFormatterFactory c = new DefaultFormatterFactory(b);
humidityLevel.setFormatterFactory(c);
}

J'ai essayé aussi de mettre un humidityLevel à nouveau champ de texte formaté en vain.

Principalement c'est que ce morceau de code:

public void HumidityLevel()
{
NumberFormat a = NumberFormat.getNumberInstance();
NumberFormatter b = new NumberFormatter(a);
DefaultFormatterFactory c = new DefaultFormatterFactory(b);
humidityLevel.setFormatterFactory(c);
}

et ce bit:

private void formWindowGainedFocus(java.awt.event.WindowEvent evt) {                                       
//TODO add your handling code here:
PositionHiSera();
try {
Thread.sleep(1000);
} catch (InterruptedException ex) {
Logger.getLogger(Main.class.getName()).log(Level.SEVERE, null, ex);
}
//make Intro Disappear and make Weather Options Appear
WeatherOptions.setVisible(true);
Intro.setVisible(false);
HumidityLevel();
out.println("tests");
}                                      

Aussi, je ne veux pas utiliser un JTextField parce que je veux apprendre comment utiliser JFormattedTextField.

toutes les bonnes idées sont tués par l'aide de Fil.sleep(1000); en bref, de ne jamais utiliser Thread.sleep(int); en Java, ni dans les Swing
Grâce mkorbel, je suis à la recherche maintenant
