实现了基于TCP的Java Socket编程实例代码

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(); 
        } 
    } 
}
