Java Socket编程之简单的C/S一对一的实现

Server:

package com.wjy.server;

import java.awt.BorderLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.io.DataInputStream;
import java.io.DataOutputStream;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.ServerSocket;
import java.net.Socket;

import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JTextArea;
import javax.swing.JTextField;

        showText.append("Connect successd.\n");
        dataInputStream=new DataInputStream(socket.getInputStream());
        dataOutputStream=new DataOutputStream(socket.getOutputStream());
        while (true) {
            showText.append("Client said: "+dataInputStream.readUTF()+"\n");

@Override
public void actionPerformed(ActionEvent e) {
    // TODO Auto-generated method stub
    try {
        dataOutputStream.writeUTF(inputText.getText());
        dataOutputStream.flush();   //本人一直把这个程序调试不通，最后发现没加这句话导致服务端显示不了客户端的输入。
        showText.append("I said: "+inputText.getText()+"\n");
    } catch (IOException e1) {
        // TODO Auto-generated catch block
        e1.printStackTrace();
    }
}
}

Client:

package com.wjy.client;

import java.awt.BorderLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.io.DataInputStream;
import java.io.DataOutputStream;
import java.io.IOException;

import java.net.UnknownHostException;
