模拟用Java按下的键

Thread.sleep（）阻止当前线程（按住键的线程）执行。

如果希望它在给定的时间内按住键，也许应该在并行线程中运行它。

这是一个解决Thread.sleep（）问题的建议（使用命令模式，以便您可以创建其他命令并随意交换它们）：

public class Main {public static void main(String[] args) throws InterruptedException {    final RobotCommand pressAKeyCommand = new PressAKeyCommand();    Thread t = new Thread(new Runnable() {        public void run() { pressAKeyCommand.execute();        }    });    t.start();    Thread.sleep(5000);    pressAKeyCommand.stop();  }}class PressAKeyCommand implements RobotCommand {private volatile boolean isContinue = true;public void execute() {    try {        Robot robot = new Robot();        while (isContinue) { robot.keyPress(KeyEvent.VK_A);        }        robot.keyRelease(KeyEvent.VK_A);    } catch (AWTException ex) {        // Do something with Exception    }}  public void stop() {     isContinue = false;  }}interface RobotCommand {  void execute();  void stop();}
