display a label after the Button is clicked in Java swing

I want to display a label, when a button is clicked. I am using Eclipse Juno. I have the label added and setting the visible part...

wLabel = new JLabel("YOu and Me");
    wLabel .setVisible(false);
    wLabel .setBounds(80, 35, 100, 25);
    wLabel .setFont(new Font("Meiryo", Font.PLAIN, 9));
    wLabel .setForeground(new Color(255, 102, 21));
    add(wLabel);

the button

wButton = new JButton("W");
    wButton .setActionCommand("myButton");
    wButton .addActionListener(this);
    wButton .setFont(new Font("Meiryo UI", Font.PLAIN, 11));
    wButton .setBounds(10, 33, 70, 35);
    wButton .setBackground(new Color(102, 51, 20));
    add(wButton);

and here is the actionPerformed. I already implemented ActionListener

public void actionPerformed(ActionEvent e) {
    // TODO Auto-generated method stub
    if (e.getActionCommand().equals("myButton")) {
        wLabel.setVisible(true);

    }
}

public NewJFrame() {
    initComponents();
    jLabel1.setVisible(false);
}

private void initComponents(){
     jLabel1 = new javax.swing.JLabel();
    jButton1 = new javax.swing.JButton();

    setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE);

    jLabel1.setText("jLabel1");

    jButton1.setText("jButton1");
    jButton1.addActionListener(new java.awt.event.ActionListener() {
        public void actionPerformed(java.awt.event.ActionEvent evt) {
            jButton1ActionPerformed(evt);
        }
    });}




   private void jButton1ActionPerformed(java.awt.event.ActionEvent evt)   {                                         
    jLabel1.setVisible(true);
}

This piece of code worked for me, Here NewJFrame() is the constructor

Add ActionListener to your button:

wButton.addActionListener(new ActionListener() {
    public void actionPerformed(ActionEvent e) {
         //Execute when button is pressed
         wLabel.setVisible(true);
    }
});

Or better practice (I think) is to create separate class that implements ActionListener. But result will be the same. I don't know how big your application is, but I suggest to separate ActionListeners (like separate class I mentioned), just to make your code clear.

Initially you can set the visibility to false of your label and after clicking the button set the visibility like label.setVisible(true)

for e.g. like this, note i am using lamba syntax for java 8

import java.awt.Dimension;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;

public class BtnDisabled {

    public static void main(String[] args) {

        JFrame frame = new JFrame("");
        JLabel label = new JLabel("You and Me");
        label.setVisible(false);
        JPanel panel = new JPanel();
        panel.add(label);

        JButton btn = new JButton("W");
    btn.addActionListener(e -> {
        if (!label.isVisible()) {
            label.setVisible(true);
        }
    });
        panel.add(btn);
        frame.add(panel);
        frame.setSize(new Dimension(500, 500));

        frame.setVisible(true);
    }
}
