客户端：

package c;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.PrintWriter;
import java.net.InetAddress;
import java.net.Socket;
import java.net.UnknownHostException;
import java.util.Scanner;

public class Client {
	public static PrintWriter out;
	public static void main(String[] args) throws UnknownHostException, IOException {
		System.out.println("客户端启动............");
		Socket socket = new Socket(InetAddress.getLocalHost(),4215);
		out = new PrintWriter(socket.getOutputStream());
		BufferedReader in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
		while(true){
			out.println(new Scanner(System.in).next());
			out.flush();
			System.out.println("服务器:"+in.readLine());
			
		}
	}
	
}

 服务器端：

package s;

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

public class Server {
	public static void main(String[] args) throws Exception {
		
		ServerSocket ss = new ServerSocket(4215);
		Socket socket = ss.accept();
		System.out.println("服务器启动");
		BufferedReader in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
		PrintWriter out = new PrintWriter(socket.getOutputStream());
		
		while(true){
			System.out.println("客户端:"+in.readLine());
			out.println(new Scanner(System.in).next());
			out.flush();
		}
	}
