Java求助：keypressed无法被引用

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class jkll {
	
	public static void createAndShowGUI() {
		JFrame frame=new JFrame("test");
		frame.setLayout(new FlowLayout());
		frame.setLocation(300, 200);//确定窗口位置
		JTextField tf=new JTextField(40);//创建文本框
		frame.add(tf);
		frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		frame.setSize(500,300);
		frame.setVisible(true);
		tf.addKeyListener(new KeyAdapter() {
			public void keypressed(KeyEvent e) {
				char ch=e.getKeyChar();
				System.out.println(ch);
			}	
			});
		}
	public static void main(String[] args) {
   	 SwingUtilities.invokeLater(jkll::createAndShowGUI);
}
}

代码如上，第十五行的keypressed一直报错“The method keypressed(KeyEvent e) from the new KeyAdapter() is not used locally”，该怎么解决？求助各位大佬

大小写有问题
