如何在Java中使用Robot类

　　Java.awt.Robot 类用于控制鼠标和键盘。一旦你得到这种控制，你能够通过你的Java代码做与鼠标和键盘任何类型的操作。这个类通常用于自动化测试。先面的代码样例将向您展示Robot类如何处理键盘事件。如果你运行此代码，并打开notepad，您将在notepad中看到HI CAOER.赶快试一试吧。

import java.awt.AWTException;

import java.awt.Robot;

import java.awt.event.KeyEvent;

public class RobotExp {

public static void main(String[] args) {

try {

Robot robot = new Robot();

//定义5秒的延迟以便你打开notepad 哈哈

// Robot 开始写

robot.delay(5000);

robot.keyPress(KeyEvent.VK_H);

robot.keyPress(KeyEvent.VK_I);

robot.keyPress(KeyEvent.VK_SPACE);

robot.keyPress(KeyEvent.VK_C);

robot.keyPress(KeyEvent.VK_A);

robot.keyPress(KeyEvent.VK_O);

robot.keyPress(KeyEvent.VK_E);

robot.keyPress(KeyEvent.VK_R);

} catch (AWTException e) {

e.printStackTrace();

}

}

      }

　　网友完善了以上代码：

import java.awt.AWTException;

import java.awt.Robot;

import java.awt.event.KeyEvent;

import java.io.IOException;



public class RobotExp {

public static void pressKey(Robot robot, int keyvalue) {

robot.keyPress(keyvalue);

robot.keyRelease(keyvalue);

}

public static void pressKeyWithShift(Robot robot, int keyvalue) {

robot.keyPress(KeyEvent.VK_SHIFT);

robot.keyPress(keyvalue);

robot.keyRelease(keyvalue);

robot.keyRelease(KeyEvent.VK_SHIFT);

}

public static void closeApplication(Robot robot) {

// pressKey(robot, KeyEvent.VK_ALT);

// pressKey(robot, KeyEvent.VK_F4);

robot.keyPress(KeyEvent.VK_ALT);

robot.keyPress(KeyEvent.VK_F4);

robot.keyRelease(KeyEvent.VK_ALT);

robot.keyRelease(KeyEvent.VK_F4);

//for linux.

// robot.keyPress(KeyEvent.VK_ALT);

// robot.keyPress(KeyEvent.VK_W);
