package firstword;
import java.net.*;
import javax.net.*;
import java.io.*;
public class Communication extends Thread{
int indata ,outdata;
char buffer[]=new char[8192];
public Communication() {
try{
Socket csocket = new Socket(jTextArea3.getText(),80);
BufferedReader in =new BufferedReader(new BufferedInputStream(csocket.getInputStream()));
PrintWriter out = new PrintWriter(csocket.getOutputStream());
}catch(IOException e){ }
}

public void run(){
while(true){
indata =in.read(buffer);
if(indata==-1)
break;
}//end while
String indata_s=new String(buffer);
jTextArea2.append("服务器端:"+indata);
}//end run
Communication communication=new Communication();
}

以上是我用JBuilder编写的一部分程序.jTextArea3上一个警告:说这个变量无法找到. jTextArea3是jTextArea类型的变量,在JJJ.JAVA文件里定义的.JJJ.JAVA文件和Communication.java同在一个包下.请问上述问题如何解决.在线等待解答.
