实现了基于TCP的Java Socket编程实例代码_java

分享到:

实现了基于TCP的Java Socket编程,功能很简单:客户端向服务器端输出一名话"connect",服务器端接收输出到控制台并向客户端输出一名话"Hello",客户端接收并输出。

1.服务器端

package javase.net.socket; 

import java.io.DataInputStream; 
import java.io.DataOutputStream; 
import java.io.IOException; 
import java.io.InputStream; 
import java.io.OutputStream; 
import java.net.ServerSocket; 
import java.net.Socket; 

public class TCPServer { 
    public static void main(String[] args) { 
        try { 
            ServerSocket serverSocket = new ServerSocket(8888); 
            Socket socket = serverSocket.accept(); 
            // 读取客户端数据 
            InputStream info = socket.getInputStream(); 
            DataInputStream dis = new DataInputStream(info); 
            System.out.println(dis.readUTF()); 

            // 向客户端输出数据 
            OutputStream os = socket.getOutputStream(); 
            DataOutputStream dos = new DataOutputStream(os); 
            dos.writeUTF("Hello!"); 
            dos.flush(); 
        } catch (IOException e) { 
            e.printStackTrace(); 
        } 
    } 

2.客户端:

package javase.net.socket; 

import java.io.DataInputStream; 
import java.io.DataOutputStream; 
import java.io.IOException; 
import java.io.InputStream; 
import java.io.OutputStream; 
import java.net.Socket; 
import java.net.UnknownHostException; 

public class TCPClient { 
    public static void main(String[] args) { 
        try { 
            Socket socket = new Socket("192.168.1.123", 8888); 
            // 向服务器端发送数据 
            OutputStream os =  socket.getOutputStream(); 
            DataOutputStream bos = new DataOutputStream(os); 
            bos.writeUTF("Connect"); 
            bos.flush(); 

            // 接收服务器端数据 
            InputStream is = socket.getInputStream(); 
            DataInputStream dis = new DataInputStream(is); 
            System.out.println(dis.readUTF()); 
        } catch (UnknownHostException e) { 
            e.printStackTrace(); 
        } catch (IOException e) { 
            e.printStackTrace(); 
        } 
    }
