如何在SWT KeyListener中检测3次按键

import org.eclipse.swt.SWT;
import org.eclipse.swt.events.KeyEvent;
import org.eclipse.swt.events.KeyListener;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Shell;

public class KeyListenerExample {
    private static int keyCount = 0;

    public static void main(String[] args) {
        Display display = new Display();
        Shell shell = new Shell(display);

        shell.addKeyListener(new KeyListener() {
            @Override
            public void keyPressed(KeyEvent e) {
                if (e.keyCode == SWT.KEYPAD_1) { // 检测按下的按键是否为数字键盘的1
                    keyCount++;
                    if (keyCount == 3) {
                        System.out.println("按键次数达到3次");
                        // 执行相应的操作
                        keyCount = 0; // 重置计数器
                    }
                }
            }

            @Override
            public void keyReleased(KeyEvent e) {
                // 不需要做任何操作
            }
        });

        shell.open();
        while (!shell.isDisposed()) {
            if (!display.readAndDispatch()) {
                display.sleep();
            }
        }
        display.dispose();
    }
}
