Java에서 키보드 입력을 시뮬레이션하는 방법: 간단한 접근 방식과 사용자 정의 키 처리

<code class="java">import static java.awt.event.KeyEvent.*;

public class KeystrokeSimulator {

    public static void main(String[] args) {
        String input = "Example Keystrokes";
        int keycode;

        // Initialize the Robot for key event simulation
        Robot robot = new Robot();

        // Loop through each character
        for (char character : input.toCharArray()) {
            switch (character) {
                case 'a': keycode = VK_A; break;
                case 'b': keycode = VK_B; break;
                // ... continue for all characters
                default: keycode = 0; // Unknown character
            }

            if (keycode != 0) {
                robot.keyPress(keycode);
                robot.keyRelease(keycode);
            }
        }
    }
}</code>

<code class="java">import static java.awt.event.KeyEvent.*;

public class CustomKeystrokeSimulator extends KeystrokeSimulator {

    public CustomKeystrokeSimulator(Robot robot) {
        super(robot);
    }

    @Override
    public void type(char character) {
        super.type(character);
        // Custom handling for special characters or key combinations
        // (e.g., mapping '!' to Shift + '1')
    }
