Methods of PointerInfo

Method	Explanation
getDevice()	Returns the graphics device on which mouse was present when the object was created .
getLocation()	Returns a point object that gives the location of the mouse pointer.

Example Program to find the number of buttons on the Mouse

// Java Program to find the number of 
// buttons on the mouse 
import java.awt.*; 
import javax.swing.*; 
  
class numberofbuttons { 
  
    // Main Method 
    public static void main(String args[]) 
    { 
        int numberofbuttons; 
  
        // number of buttons in the mouse 
        numberofbuttons = MouseInfo.getNumberOfButtons(); 
  
        // print the number of buttons 
        System.out.println("Number of buttons on the mouse =" 
                                           + numberofbuttons); 
    } 
} 

Output:

Number of buttons on the mouse = 5

Example Program to show the Position of Mouse

// Java Program to show the 
// position of mouse 
import java.awt.*; 
import java.awt.event.*; 
import javax.swing.*; 
  
class mouse extends JFrame { 
  
    boolean b; 
  
    // label 
    JLabel l, l1; 
  
    // Main Method 
    public static void main(String args[]) 
    { 
  
        // create object 
        mouse m = new mouse(); 
    } 
  
    // default constructor 
    mouse() 
    { 
        super("mouse"); 
  
        // create labels 
        l = new JLabel(""); 
        l1 = new JLabel(""); 
  
        // create a panel 
        JPanel p = new JPanel(); 
  
        // add labels to panel 
        p.add(l); 
        p.add(l1); 
  
        add(p); 
        show(); 
        setSize(300, 300); 
  
        b = true; 
        execute(); 
    } 
  
    public void execute() 
    { 
        while (b) { 
            // get the pointer info object from the mouseInfo 
            PointerInfo pi = MouseInfo.getPointerInfo(); 
  
            // get the location of mouse 
            Point p = pi.getLocation(); 
  
            // set the text of labels 
            l.setText("x position =" + p.getX()); 
            l1.setText("y position =" + p.getY()); 
        } 
    } 
}
