    Default Button Text into Label text

    Write a program that has three buttons, each displaying a different text that when pressed will display the text on the button in a text box. That was my task, and here is my code:

    import java.awt.*;
    import java.awt.event.*;
    import javax.swing.*;
    import java.lang.String;
     
    public class MouseClick
    {
    Label objLabel1;
    Label objLabel2;
    Label objLabel3;
    public static void main(String[] args)
    {
    MouseClick MC= new MouseClick();
    }
     
    public MouseClick()
    {
    JFrame f = new JFrame("JFrame");
    final JPanel p1 = new JPanel();
    Button a = new Button("A");
    a.setBounds(20,30,40,40);
    JButton b = new JButton("B");
    b.setBounds(85,75, 40, 40);
    JButton c = new JButton("C");
    c.setBounds(130, 120, 40, 40);
    p1.add(a);
    p1.add(b);
    p1.add(c);
    f.getContentPane().add(p1);
     
    objLabel1 = new Label("A");
    objLabel1.setBounds(20,75,40,40);
    objLabel2 = new Label("B");
    objLabel2.setBounds(85,120,40,40);
    objLabel3 = new Label("C");
    objLabel3.setBounds(130,185,40,40);
    p1.add(objLabel1);
    objLabel1.setVisible(false);
    p1.add(objLabel2);
    objLabel2.setVisible(false);
    p1.add(objLabel3);
    objLabel3.setVisible(false);
    f.addWindowListener(new WindowAdapter()
    {
    public void windowClosing(WindowEvent we)
    {
    System.exit(0);
    }
    });
    f.setSize(400,400);
    f.setVisible(true);
    }
     
    public class MyMouseListener extends MouseAdapter
    {
    public void mouseClicked(MouseEvent me)
    {
    //String stra = me.getActionCommand ("A");
    //objLabel1.setText (stra);
    //String strb = me.getActionCommand ("B");
    //objLabel1.setText (strb);
    //String strc = me.getActionCommand ("C");
    //objLabel1.setText (strc);
    Label objLabel1;
    Label objLabel2;
    Label objLabel3;
    objLabel1.setVisible(true);
    objLabel2.setVisible(true);
    objLabel3.setVisible(true);
    }
    }
    }

    I originally used Strings, but it wasn't working. right now the error i'm getting is that the objLabels havent been initialized. Help? thanks!

    Default Re: Button Text into Label text

    Don't forget highlight tags when posting code.

    Did you google that error?

    Hint: Why are you re-declaring objLabel1, 2 and 3? What value do they have when you declare them in your mouseClicked() method?

    And again, why are you mixing Swing and Awt? Why are you using Labels instead of JLabels?
