Change the `JLabel` Text in Java Swing

The method setText() can be used to update the text of JLabel in Swing. In Java, we create a frame where the label will be changed if we press the button.

Follow the steps below:

First of all, create a JFrame and set the size.
Now, create the first label with the original text label.
Create a button to change the label.
Add an action listener to the button.
Add the setText method to the action listener and change the text for JLabel.
Finally, run the program, and the JLabel text will be changed when the button is clicked.

Let’s implement the program in Java based on the steps above:

package delftstack;

import java.awt.BorderLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.*;

public class Change_Jlabel {
  public static void main(String args[]) {
    JFrame Demo_Frame = new JFrame("Demo Frame");
    Demo_Frame.setLayout(new BorderLayout());
    Demo_Frame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
    Demo_Frame.setSize(250, 100);

    final JLabel J_Label = new JLabel("Original Label");
    JButton J_Button = new JButton("Change Label");
    J_Button.addActionListener(new ActionListener() {
      @Override
      public void actionPerformed(ActionEvent arg0) {
        J_Label.setText("New Label");
      }
    });

    Demo_Frame.add(J_Label, BorderLayout.NORTH);
    Demo_Frame.add(J_Button, BorderLayout.CENTER);
    Demo_Frame.setVisible(true);
  }
}

See the output for the code above:
