我用的是英文版的eclipse，jdk1.6
做到是基于C/S的一个聊天软件，代码如下：
package client;
import java.io.IOException;
import java.io.EOFException;
import java.io.ObjectInputStream;
import java.io.ObjectOutputStream;
import java.net.Socket;
import java.util.ArrayList;
import java.util.Iterator;
import common.TextMessage;
/**
* simple chat client
*/
public class Client implements Runnable {
public static void main(String args[]) throws IOException {
if (args.length != 2)
throw new RuntimeException("Syntax: ChatClient <host> <port>");
Client client = new Client(args[0], Integer.parseInt(args[1]));
new Gui("Chat " + args[0] + ":" + args[1], client);
}
protected ObjectInputStream inputStream;
protected ObjectOutputStream outputStream;
protected Thread thread;
public Client(String host, int port) {
try {
System.out.println("Connecting to " + host + " (port " + port
+ ")...");
Socket s = new Socket(host, port);
this.outputStream = new ObjectOutputStream((s.getOutputStream()));
this.inputStream = new ObjectInputStream((s.getInputStream()));
System.out.println("AAA");
thread = new Thread(this);
thread.start();
} catch (Exception e) {
e.printStackTrace();
}
}
/**

*/
public void run() {
try {
Thread thisthread = Thread.currentThread();
while (thread == thisthread) {
try {
Object msg = inputStream.readObject();
handleIncomingMessage(msg);
} catch (EOFException e) {
e.printStackTrace();

}
}
} catch (IOException ex) {
ex.printStackTrace();
} finally {

try {

}
}
}
