2. Java Program to Take Screenshots

There might be a situation where you guys want to take screen shots programmatically. So I am sharing a program that help you to take screen capture of your screen and save it in PNG (Portable network graphic) picture format.

The below program uses Java.awt.Robot class to capture the screen pixels and uses Imageio to save it as PNG image format. Just copy and paste the program in Notepad, save it and run the program to take screen shot.

Note: The Screen shot image will be stored at the location where your program is stored.

02import java.awt.Robot;

03import java.awt.Toolkit;

06import javax.imageio.*;

13  BufferedImage Entire_Screen = awt_robot.createScreenCapture(newRectangle(Toolkit.getDefaultToolkit().getScreenSize()));

14  ImageIO.write(Entire_Screen, "PNG", new File("Entire_Screen.png"));
