有谁既会AWT又会SWING的？

Question

有一道题，要把AWT改写成SWING的；
其中AWT的程序是这样：
import java.awt.*;
import java.awt.event.*;
public class TestAnonymous{
Frame f=new Frame("匿名内部类测试");
TtextField tf=new TextField(30);
public TestAnonymous(){
f.add(new Label("请按下鼠标左键并拖动"),"North");
f.add(tf,"South");
f.addMouseMotionListener(new MouseMotionListener(){
public void mouseDragged(MouseEvent e){
String s="鼠标拖动到位置("+e.getX()+","+e.getY()+")";
tf.setText(s);
}
public void mouseMoved(MouseEvent e){}
});
   f.addWindowListener(new windowAdapter(){
      public viod windowClosing(windowEvent e){
       System.exit(0);
       }
       });
       f.setSize(300,200);
       f.setVisible(true);
      }
      public static void main(String args[]){
       TextAnonymous t=new TestAnonymous();
      }
     
      }
  哪位好心人提点一下，我知道就是把组键前加J，后面添个内容面板。但做出来不对

     contentPane.add(cards,BorderLayout.CENTER);
      }
    }

提示我：E:\jjj\TestAnonymous.java:29: <identifier> expected
     contentPane.add(cards,BorderLayout.CENTER);

我对JAVA学的不好哈，所以很郁闷

Answer 3

'class' or 'interface' expected
一般是大括号不匹配cannot resolve symbol
是你没有引入类。

Answer 4

1. 中间有很多的拼写错误.
2. 有一些括号不匹配的错误.
3. contentPane.add(cards,BorderLayout.CENTER)需要放在一个方法内.建议先改正拼写错误.

Answer 5

经过修改变成这样：
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.border.*;
public class TestAnonymous{
JFrame f=new JFrame("匿名内部类测试");
JTextField tf=new JTextField(30);
public TestAnonymous(){
f.add(new JLabel("请按下鼠标左键并拖动"),"North");
f.add(tf,"South");
f.addMouseMotionListener(new MouseMotionListener(){
public void mouseDragged(MouseEvent e){
String s="鼠标拖动到位置("+e.getX()+","+e.getY()+")";
tf.setText(s);
}
public void mouseMoved(MouseEvent e){}
});
   f.addWindowListener(new WindowAdapter(){
      public viod windowClosing(WindowEvent e){
       System.exit(0);
       }
       });
       f.setSize(300,200);
       f.setVisible(true);
      }
      public static void main(String args[]){
       TextAnonymous t=new TestAnonymous();
      }
     public static void main(){
     frame.contentPane.add(cards,BorderLayout.CENTER);
     }
     
    }
但还是错的

提示：
E:\jjj\TestAnonymous.java:19: cannot resolve symbol
symbol: class viod

      }
     public static void main(){

还错了两个地方了，全集中在加内容面板那，哪位好心人帮我解决下嘛

gtlang78果然是高手，编译出来确实没错，我还想问个白痴性的问题，我用的JCreator怎样看运行结果哦？刚开始的时候建的文件是什么文件呢？
