Detect Left, Middle, and Right Mouse Click – Java

In this tutorial, we are going to see how to use MouseAdapter to detect left, middle and right mouse click in Java. This is very useful when you want to add extra functionality to your application. You can make your application behave differently depending on which mouse button the user pressed. Also we’ll see how to get the x and y positions of the mouse on click.

  {
    if ((e.getModifiers() & InputEvent.BUTTON1_MASK) != 0) {
     System.out.println("Left click detected : " + (e.getPoint()));
    }
 
    if ((e.getModifiers() & InputEvent.BUTTON3_MASK) != 0) {
     System.out.println("Right click detected : " + (e.getPoint()));
    }
 
    if ((e.getModifiers() & InputEvent.BUTTON2_MASK) != 0) {
     System.out.println("Middle click detected : " + (e.getPoint()));
    }
  }
}
 
public class Main 
{
  public static void main(String[] argv) throws Exception 
  {
      JTextArea text = new JTextArea();
      text.addMouseListener(new CheckMouse());
      JFrame f = new JFrame();
      f.add(text);
      f.setSize(300, 300);
      f.setVisible(true);
