java如何处理键盘上“回车”键的输入？

import java.awt.event.KeyEvent;
import java.awt.event.KeyListener;

public class EnterKeyListener implements KeyListener {
    @Override
    public void keyPressed(KeyEvent e) {
        if (e.getKeyCode() == KeyEvent.VK_ENTER) {
            // 执行相应的操作
            System.out.println("回车键被按下");
        }
    }

    @Override
    public void keyTyped(KeyEvent e) {
        // 不需要实现
    }

    @Override
    public void keyReleased(KeyEvent e) {
        // 不需要实现
    }
}

import javax.swing.JFrame;
import javax.swing.JTextField;

public class Main {
    public static void main(String[] args) {
        JFrame frame = new JFrame("键盘事件示例");
        JTextField textField = new JTextField();

        // 注册监听器
        textField.addKeyListener(new EnterKeyListener());

        frame.add(textField);
        frame.setSize(300, 200);
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.setVisible(true);
    }
}
