帮忙改改这个程序
我想从一个text中输入字符然后从另一个textArea 中输出要用线程编写


import java.io.*;
import java.util.*;
import java.awt.*;
import javax.swing.*;
import java.awt.event.*;

public class Ms extends JFrame implements ActionListener{
  
class Message1{
  JTextField t1=new JTextField();
  }
  Message1 message1=new Message1();
  JPanel p1=new JPanel();
  JPanel p2=new JPanel();
  JButton b1=new JButton("send");
  JButton b2=new JButton("Close");
  Container cp=getContentPane();
  String message;
  Ms(){
    message1.t1.setEditable(false);
    setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    p1.setLayout( new FlowLayout());
    p1.add(b1,FlowLayout.LEFT);
    p1.add(b2,FlowLayout.RIGHT);
    p2.setLayout(new FlowLayout());
    p2.add(message1.t1,FlowLayout.CENTER);
    cp.setLayout(new BorderLayout(5,5));
    cp.add(p1,BorderLayout.SOUTH);
      cp.add(p2,BorderLayout.CENTER);
  }
  public void actionPerformed(ActionEvent e){
    if(e.getSource()==b1){
      message = message1.t1.getText();
      MsThread mm = new MsThread();
      mm.setMessgae(message);
      mm.start();
    }
  }

class MsThread extends Thread{
  Message2 message2=new Message2();
  String m;
  public void setMessgae(String ss){
      m = ss;
    
  }
  public void run(){
    message2.t2.setText()=m;
  }
}

class Message2 extends JFrame {
  JTextArea t2=new JTextArea(10,40);
  Message2(){
    setSize(300,200);
    setTitle("talk");
    
    addWindowListener(new WindowAdapter(){
      public void windowClosing(WindowEvent e){
        System.exit(0);
      }
    });
  }
}
public void hh(){
  Ms k=new Ms();
  k.show();
}

public static void main(String args[]){
    Ms m=new Ms();
    m.hh();
  }
}
