change language English French label

[Nouf Nassri]

Hello everyone

I want to change the language of an application and for that I did a little test, I have a label and a button I'm worth when I click on the button the label name changed <name> <nom>

  


import java.util.Locale;
import java.util.MissingResourceException;
import java.util.ResourceBundle;
import javax.swing.JOptionPane;


public class ChangeLang extends javax.swing.JFrame {

   public static ResourceBundle resourse;

    public ChangeLang() {
          try {
            resourse = ResourceBundle.getBundle("Language",Locale.getDefault());
        } catch (MissingResourceException mre) {
      mre.printStackTrace();
        }
        
        initComponents();
      

    }

  
    private void initComponents() {

        label = new javax.swing.JLabel();
        button = new javax.swing.JButton();

        setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE);

        label.setText(resourse.getString("lbl")); //---------------------Name  Label

        button.setText("Change");
        button.addActionListener(new java.awt.event.ActionListener() {
            public void actionPerformed(java.awt.event.ActionEvent evt) {
                buttonActionPerformed(evt);
            }
        });

      
    }

    private void buttonActionPerformed(java.awt.event.ActionEvent evt) {
    resourse=ResourceBundle.getBundle("Language",Locale.ENGLISH );
        //Locale.setDefault(Locale.ENGLISH);
    }

    /**
    * @param args the command line arguments
    */
    public static void main(String args[]) {
        java.awt.EventQueue.invokeLater(new Runnable() {
            public void run() {
                new ChangeLang().setVisible(true);
            }
        });
    }

    private javax.swing.JButton button;
    private javax.swing.JLabel label;


}

//Language.proprietes
lbl=name

//Language_fr.proprietes
lbl=nom

  

thank you

When the user clicked change, you loaded the bundle for English locale. After that.....?

In your buttonActionPerformed() method, you set your resource variable to the resource bundle for English, but then don't do anything with it. I think you probably want to change the label on your JLabel control.

It this isn't clear why, just consider that the way the application is currently coded, you set the label on the JLabel control only when you create the application (in the initComponents() method).

Also, I see when you click the button you change from the default language to English. What is the default language? If it's English, you won't see any change anyway.

Finally, you should use import statements to import your javax.swing components, and not use the fully-qualified class name when referencing them in the code. The way you have it now makes it harder to read.
