Server:

package cn.itcast.framework.socket;
    
    import java.io.BufferedReader;
    import java.io.IOException;
    import java.io.InputStreamReader;
    import java.io.PrintWriter;
    import java.net.ServerSocket;
    import java.net.Socket;
    
    //用JAVA SOCKET编程，读服务器几个字符，再写入本地显示？ 
    //Server端程序:
    public class Server {
    
    	private ServerSocket serverSocket;
    	private Socket socket;
    	private BufferedReader in;
    	private PrintWriter out;
    	
    	public Server(){
    		try {
    			serverSocket = new ServerSocket(10000);
    			while(true){
    				socket = serverSocket.accept();
    				String RemoteIP = socket.getInetAddress().getHostAddress();
    				String RemotePort = ":"+socket.getLocalPort();
    				System.out.println("A client come in!IP:"+RemoteIP+RemotePort);
    				in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
    				String line = in.readLine();
    				System.out.println("Client send is :"+line);
    				out = new PrintWriter(socket.getOutputStream(),true);
    				out.println("Your Message Received!");
    				out.close();
    				in.close();
    				socket.close();
    			}
    		} catch (IOException e) {
    			out.println("wrong");
    		}
    	}
    	
    	public static void main(String[] args){
    		new Server();
    	}
    }

**Client:**

package cn.itcast.framework.socket;
    
    import java.io.BufferedReader;
    import java.io.IOException;
    import java.io.InputStreamReader;
    import java.io.PrintWriter;
    import java.net.Socket;
    
    public class Client {
    
    	Socket socket;
    	BufferedReader in;
    	PrintWriter out;
    	
    	public Client(){
    		try {
    			System.out.println("Try to Connect to 127.0.0.1:10000");
    			socket = new Socket("127.0.0.1",10000);
    			System.out.println("The Server Connected!");
    			System.out.println("Please enter some Character:");
    			BufferedReader line = new BufferedReader(new InputStreamReader(System.in));
    			out = new PrintWriter(socket.getOutputStream(),true);
    			out.println(line.readLine());
    			in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
    			System.out.println(in.readLine());
    			out.close();
    			in.close();
    			socket.close();
    			
    		} catch (IOException e) {
    			out.println("Wrong");
    		}
    	}
    	
    	public static void main(String [] args){
    		new Client();
    	}
    }
