哪位大姥，知道Java如何按下f键后自动按下c键和g键

Question

    try {
        robot = new Robot();
    } catch (AWTException e) {
        e.printStackTrace();
        return;
    }

 
    Frame frame = new Frame();
    frame.setSize(1, 1);
    frame.setVisible(true);
    frame.addKeyListener(new KeyAdapter() {
        @Override
        public void keyPressed(KeyEvent e) {
            if (e.getKeyCode() == KeyEvent.VK_F) {
                // 模拟按下 C 键
                robot.keyPress(KeyEvent.VK_C);
                robot.keyRelease(KeyEvent.VK_C);
                // 模拟按下 G 键
                robot.keyPress(KeyEvent.VK_G);
                robot.keyRelease(KeyEvent.VK_G);
            }
        }
    });

    // 使程序保持运行，直到用户关闭窗口
    frame.addWindowListener(new java.awt.event.WindowAdapter() {
        public void windowClosing(java.awt.event.WindowEvent windowEvent) {
            frame.dispose();
            System.exit(0);
        }
    });

    try {
        java.awt.EventQueue.invokeAndWait(() -> {
            while (true) {
                try {
                    Thread.sleep(100); // 减少 CPU 占用
                } catch (InterruptedException ex) {
                    ex.printStackTrace();
                }
            }
        });
    } catch (Exception ex) {
        ex.printStackTrace();
    }
}

}

import java.awt.*;
import java.awt.event.*;

public class KeySimulator {
    public static void main(String[] args) {
        Robot robot = null;
        try {
            robot = new Robot();
        } catch (AWTException e) {
            e.printStackTrace();
            return;
        }

        Frame frame = new Frame();
        frame.setSize(1, 1);
        frame.setUndecorated(true); // 可以设置为无边框窗口
        frame.setVisible(true);
        frame.addKeyListener(new KeyAdapter() {
            @Override
            public void keyPressed(KeyEvent e) {
                if (e.getKeyCode() == KeyEvent.VK_F) {
                    // 模拟按下 C 键
                    robot.keyPress(KeyEvent.VK_C);
                    robot.keyRelease(KeyEvent.VK_C);

                System.exit(0);
            }
        });

        // 保持窗口运行
        while (true) {
            try {
                Thread.sleep(100); // 减少 CPU 占用
            } catch (InterruptedException ex) {
                ex.printStackTrace();
