Java服务器与客户端的连接

客户端程序

server.java

package com.sram.sever;
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.io.OutputStream;
import java.io.PrintStream;
import java.net.ServerSocket;
import java.net.Socket;
public class Sever {
	public static void main(String[] args) throws Exception{
		ServerSocket serverSocket =new ServerSocket(5555);
		
		System.out.println("服务端已经启动，等待客户端输入********");
		while(true)
		{
			Socket client=serverSocket.accept();
		
			//使用简单的流来输出
			//此打印流就是服务器先客户端输出的信息流
			PrintStream printstream= new PrintStream(client.getOutputStream());
			//printstream.println("liuxingruichoubi");
			
			BufferedReader readerClient = new BufferedReader(new InputStreamReader(client.getInputStream()));
			
			String clientStr=readerClient.readLine();
			
			System.out.println("接收到了---->"+clientStr);
			
			printstream.println("接收到了---->"+clientStr);
		}
	}
}
