Question

.\PoliceListen.java:3: 错误: PoliceListen不是抽象的, 并且未覆盖MyCommandListener中的

MyCommandListener.java
import javax.swing.*;
import java.awt.event.*;
public interface MyCommandListener extends ActionListener{
public void setJTextField(JTextField text);
public void setJTextArea(JTextArea area);
}

PoliceListen.java

import java.awt.event.*;
import javax.swing.*;
public class PoliceListen implements MyCommandListener{
JTextField textInput;
JTextArea textShow;
public void setJextField(JTextField text){
textInput = text;
}
public void setJTextArea(JTextArea area){
textShow = area;
}
public void actionPerformed(ActionEvent e){
String str =textInput.getText();
textShow.append(str+"的长度"+str.length()+"\n");
}
}
我怎么觉得方法好像都实现了啊，求大神帮忙

问题在这里：
public void setJextField(JTextField text){
textInput = text;
}
方法名写错了，少打了一个 "T"
