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
谢谢前辈
大小写有问题
