How can we implement a moving text using a JLabel in Java?



A JLabel is a subclass of JComponent class and an object of JLabel provides text instructions or information on a GUI. A JLabel can display a single line of read-only text, an image or both text and an image. A JLabel can explicitly generate a PropertyChangeListener interface. We can also implement a moving text in a JLabel by using a Timer class, it can set a timer with speed(in milliseconds) and this as an argument.

Example

import java.awt.*; import java.awt.event.*; import java.util.*; import javax.swing.*; import javax.swing.Timer; public class MovingTextLabel extends JFrame implements ActionListener {    private JLabel label;    public MovingTextLabel() {       setTitle("MovingTextLabel");       label= new JLabel(" Welcome to Tutorials Point ");       label.setFont(new Font("Arial", 0, 25));       add(label, BorderLayout.CENTER);       Timer t = new Timer(400, this); // set a timer       t.start();       setSize(400, 300);       setVisible(true);       setLocationRelativeTo(null);       setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);    }    public void actionPerformed(ActionEvent e) {       String oldText = label.getText();       String newText= oldText.substring(1)+ oldText.substring(0,1);       label.setText(newText);    }    public static void main (String[] args) {       new MovingTextLabel();    } }
