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。下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。
代码如下：

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
// 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：
代码如下：

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);
// robot.keyRelease(KeyEvent.VK_ALT);

}
public static void main(String[] args) throws IOException {
