java.awt.Robot 類用于控制鼠標和鍵盤。一旦你得到這種控制，你能夠通過你的Java代碼做與鼠標和鍵盤任何類型的操作。這個類通常用于自動化測試。下面的代碼樣例將向您展示Robot類如何處理鍵盤事件。如果你運行此代碼，并打開notepad，您將在notepad中看到HI CAOER.趕快試一試吧。

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();
//定義5秒的延遲以便你打開notepad
// Robot 開始寫
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();
}
}
}

網友完善了以上代碼：
