本文提供了一个简单的Java Socket通信示例，包括Server端与Client端的实现代码，演示了如何接收并显示客户端发送的消息。

就是Server端显示客户端发送到内容，比较简单。

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.PrintWriter;
import java.net.ServerSocket;
import java.net.Socket;

public class Server 
{
	private ServerSocket ss;
	private Socket socket;
	private BufferedReader in;
	private PrintWriter out;

	public Server() 
	{
		try 
		{
			ss = new ServerSocket(10000);
			
			System.out.println("The server is waiting your input...");
			
			while(true) 
			{
				socket = ss.accept();
				
				in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
				out = new PrintWriter(socket.getOutputStream(), true);
				String line = in.readLine();
				
				System.out.println("you input is : " + line);
				
				//out.println("you input is :" + line);
				
				out.close();
				in.close();
				socket.close();
				
				if(line.equalsIgnoreCase("quit") || line.equalsIgnoreCase("exit"))
					break;
			}
			
			ss.close();
			
		} catch (IOException e) {
			e.printStackTrace();
		}
	}

	public static void main(String[] args) 
	{
		new Server();
	}
}

import java.io.*;
import java.net.*;

public class Client 
{
	Socket socket;
	BufferedReader in;
	PrintWriter out;

	public Client() 
	{
		try 
		{
			socket = new Socket("127.0.0.1", 10000);
			
			in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
			out = new PrintWriter(socket.getOutputStream(), true);
			BufferedReader line = new BufferedReader(new InputStreamReader(System.in));

			out.println(line.readLine());
			
			line.close();
			out.close();
			in.close();
			
			socket.close();
			
		} catch (IOException e) {
		}
	}

	public static void main(String[] args) 
	{
		new Client();
	}
}
