Label update and numbers displaying, not only string

Question

Hi all
i'v three classes, one which creates random information "generator" and another class which displays the information.
so my question is now, how can i update the information in the display class instantly? and why can i only show strings "text" an no numbers? for example i need to display numbers too for temperature purpose.
attached are the files.
the generator class:
public class Generator extends Thread {
     public long delay;
     public boolean stopped;
     Generator() {
          delay = 2000;
          stopped = false;
     public void run() {
          while (!stopped) {
               try {
                    Thread.sleep(delay);
                    MeteoDaten meteodaten1 = new MeteoDaten();
                    // Stadt Generator
                    int stadt = (int) (Math.random() * 5) + 1;
                         if (stadt == 1) {
                              meteodaten1.getOrt();
                              meteodaten1.setOrt("Zurich");
                         if (stadt == 2) {
                              meteodaten1.getOrt();
                              meteodaten1.setOrt("Basel");
                         if (stadt == 3) {
                              meteodaten1.getOrt();
                              meteodaten1.setOrt("Bern");
                         if (stadt == 4) {
                              meteodaten1.getOrt();
                              meteodaten1.setOrt("Lausanne");
                         if (stadt == 5) {
                              meteodaten1.getOrt();
                              meteodaten1.setOrt("Genf");
                         // Temperatur Generator
                         int temp = (int) (Math.random() * 35 - Math.random() * 20) + 1;
                         meteodaten1.getTemp();
                         meteodaten1.setTemp(temp);
                         // Beschreib Generator
                         int beschreib = (int) (Math.random() * 5) + 1;
                         if (beschreib == 1) {
                              meteodaten1.getBeschreib();
                              meteodaten1.setBeschreib("Bewoelkt");
                         if (beschreib == 2) {
                              meteodaten1.getBeschreib();
                              meteodaten1.setBeschreib("Sonnig");
                         if (beschreib == 3) {
                              meteodaten1.getBeschreib();
                              meteodaten1.setBeschreib("Gewitter");
                         if (beschreib == 4) {
                              meteodaten1.getBeschreib();
                              meteodaten1.setBeschreib("Stuermisch");
                         if (beschreib == 5) {
                              meteodaten1.getBeschreib();
                              meteodaten1.setBeschreib("Bedeckt");
               } catch (InterruptedException e) {
}the other class:
class MeteoDaten {
     // Initialisierung
     public String ort, beschreib;
     public int temp;
     // Getters Setters
     public String getBeschreib() {
          return beschreib;
     public void setBeschreib(String beschreib) {
          this.beschreib = beschreib;
     public String getOrt() {
          return ort;
     public void setOrt(String ort) {
          this.ort = ort;
     public int getTemp() {
          return temp;
     public void setTemp(int temp) {
          this.temp = temp;
}and finally the label class:
import java.awt.*;
import java.awt.event.*;
import java.awt.GridLayout;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;
import javax.swing.JLabel;
import javax.swing.ImageIcon;
public class LabelFrame extends Frame {
     private static final long serialVersionUID = 1L;
     public LabelFrame() {
          setTitle("MeteoDaten");
          setBackground(Color.white);
          addWindowListener(new TestWindowListener());
          MeteoDaten meteoDaten = new MeteoDaten();
          setLayout(new GridLayout(6, 2)); // GridLayout setzen
          // Initialisierung Buttons
          Button button1, button2;
          button1 = new Button("Get Data");
          button1.addActionListener(new Test1ActionListener());
          button2 = new Button("Stop");
          button2.addActionListener(new Test2ActionListener());
          // Initialisierung Labels
          Label labelOrtlinks, labelTemplinks, labelTemprechts, labelBeschreiblinks, labelBeschreibrechts, labelVisuell;
          // Initialisierung Font
          Font bigFont = new Font("Verdana", Font.BOLD, 14);
          // Label Text Setzung
          labelOrtlinks = new Label("Ort: ");
          labelOrtlinks.setFont(bigFont);
          labelTemplinks = new Label("Temperatur:");
          labelTemplinks.setFont(bigFont);
          labelTemprechts = new Label(meteoDaten.getTemp());
          labelTemprechts.setFont(bigFont);
          labelBeschreiblinks = new Label("Beschreib: ");
          labelBeschreiblinks.setFont(bigFont);
          labelBeschreibrechts = new Label(meteoDaten.getBeschreib());
          labelBeschreibrechts.setFont(bigFont);
          labelVisuell = new Label("Visuell:");
          labelVisuell.setFont(bigFont);
          // Add First Label
          add(labelOrtlinks);
          // Ort Auswahl
          Choice choice = new Choice();
          choice.add("Zurich");
          choice.add("Basel");
          choice.add("Bern");
          choice.add("Lausanne");
          choice.add("Genf");
          add(choice);
          // Add Labels
          add(labelTemplinks);
          add(labelTemprechts);
          add(labelBeschreiblinks);
          add(labelBeschreibrechts);
          add(labelVisuell);
          // Bild
          JLabel labelpic = new JLabel(new ImageIcon("thunders.png"));
          add(labelpic);
          // Abstand
          add(new Label(""));
          add(new Label(""));
          // Buttons
          add(button1);
          add(button2);
          pack();
          setVisible(true);
          //Gr��sse vom Fenster
          setSize(300, 250);
          setVisible(true);
     class TestWindowListener extends WindowAdapter {
          public void windowClosing(WindowEvent e) {
               e.getWindow().dispose();
               System.exit(0);
     class Test1ActionListener implements ActionListener {
          public void actionPerformed(ActionEvent e) {
               System.out.println("Getting Data...");
               //Generator starten
               Generator gen1 = new Generator();
               gen1.start();
     class Test2ActionListener implements ActionListener {
          public void actionPerformed(ActionEvent e) {
               System.out.println("Stop!");
               //Generator stoppen
     public static void main(String args[]) {
          new LabelFrame();
}thank you in advance for your help!

Hello,
you can declare the label as member under the class declaration,then use labelname.setText() , like this :
public class LabelFrame extends Frame {
private JLable labelTemprechts =new JLable();
public void changeLabelValue(int newValue){
this.labelTemprechts.setText(String.valueOf(newValue));
.
