How To Press Mouse Programmatically

In this post, we will discuss how to handle mouse presses programmatically without manual intervention. This is sometimes handy when we need to perform a mouse click using the program.

Below mentioned is the code snippet showing the mouse press using Java's in-built awt class Robot.

// Create instance of Robot Class
Robot bot = new Robot();

// Move the bot position to given coordinates
bot.mouseMove( x, y );

// Press and Release the mouse to simulate click
bot.mousePress( InputEvent.BUTTON1_MASK );
bot.mouseRelease( InputEvent.BUTTON1_MASK );

System.out.println( "Mouse clicked at: " + x + " : " + y );

This is how we can simply perform a mouse click using a program. The code below further enhances it by using a simple implementation of Thread to listen for the change and perform the click.

package com.myapp.utilities;

import java.awt.AWTException;
import java.awt.Robot;
import java.awt.event.InputEvent;

public class MouseClickUtility implements Runnable {
	public static boolean active	= false;
	public static int interval	= 500;

	@Override
	public void run() {
		                         try {
                             			while( true ) {
                                                  				if( active ) {
					int mouseY = MouseInfo.getPointerInfo().getLocation().y;
					int mouseX = MouseInfo.getPointerInfo().getLocation().x;

					System.out.println( "Mouse positioned at: " + mouseY + " : " + mouseX );

					Robot bot = new Robot();

					bot.mouseMove( mouseY, mouseX );
					bot.mousePress( InputEvent.BUTTON1_MASK );
					bot.mouseRelease( InputEvent.BUTTON1_MASK );

					System.out.println( "Mouse clicked at: " + x + " : " + y );
				}
				Thread.sleep( interval );
			}
		}
		catch( InterruptedException e ) {

		e.printStackTrace();
		}

		catch( AWTException e ) {
			                   e.printStackTrace();
		}
	}
}
