Java Robot Keypress Capture

To capture key events in Java, you can use the keyPress and keyRelease methods of the Robot class. Here is a simple sample code:

import java.awt.AWTException;
import java.awt.Robot;
import java.awt.event.KeyEvent;

public class KeyPressExample {

    public static void main(String[] args) {
        try {
            Robot robot = new Robot();

            // 模拟按下和释放键
            robot.keyPress(KeyEvent.VK_A);
            robot.keyRelease(KeyEvent.VK_A);

            // 获取按下的键
            int keyCode = KeyEvent.VK_A;
            System.out.println("Key pressed: " + KeyEvent.getKeyText(keyCode));

        } catch (AWTException e) {
            e.printStackTrace();
        }
    }
}

In the example above, we used the Robot class to simulate key presses and releases, and used the getKeyText method of the KeyEvent class to get the text representation of the pressed key. After pressing a key, the program will output the text representation of the pressed key (in this example, “A”). You can modify the value of keyCode to get the text representation of other keys as needed.
