如何在Java中使用keyTyped？

import java.awt.event.KeyAdapter;
import java.awt.event.KeyEvent;

public class MyKeyListener extends KeyAdapter {
    @Override
    public void keyTyped(KeyEvent e) {
        // 在这里处理键盘输入的字符
        char c = e.getKeyChar();
        System.out.println("输入的字符是：" + c);
    }
}

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

public class Main {
    public static void main(String[] args) {
        JFrame frame = new JFrame("Java KeyTyped Example");
        JTextField textField = new JTextField();

        // 创建KeyListener对象
        KeyListener keyListener = new MyKeyListener();

        // 将KeyListener对象注册到文本框上
        textField.addKeyListener(keyListener);

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