Java - Move cursor position (Any System)

import java.awt.Robot; import java.util.Random; public class MouseMover { public static final int FIVE_SECONDS = 5000; public static final int MAX_Y = 400; public static final int MAX_X = 400; public static void main(String... args) throws Exception { Robot robot = new Robot(); Random random = new Random(); while (true) { robot.mouseMove(random.nextInt(MAX_X), random.nextInt(MAX_Y)); Thread.sleep(FIVE_SECONDS); } } }
