创建两个项目：Socket、Client

Socket为客户端， Client为服务端

==>SocketActivity.java

        /*public void run(){

            ServerSocket serverSocket = null;
            try {
                //创建一个ServerSocket对象，并让这个Socket在4567端口监听
                serverSocket = new ServerSocket(4567);
                //调用ServerSocket的accept()方法，接受客户端所发送的请求
                Socket socket = serverSocket.accept();
                //从Socket当中得到InputStream对象
                InputStream inputStream = socket.getInputStream();
                byte buffer [] = new byte[1024*4];
                int temp = 0;
                //从InputStream当中读取客户端所发送的数据
                while((temp = inputStream.read(buffer)) != -1){
                    System.out.println(new String(buffer,0,temp));
                }
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
            finally{
                try {
                    serverSocket.close();
                } catch (IOException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }
            }
        
        }*/ 
        //使用UDP协议客户端所要进行的操作  
        public void run(){ 
            try { 
                //创建一个DatagramSocket对象，并指定监听的端口号  
                DatagramSocket socket = new DatagramSocket(4567); 
                byte data [] = new byte[1024]; 
                //创建一个空的DatagramPacket对象  
                DatagramPacket packet = new DatagramPacket(data,data.length); 
                //使用receive方法接收客户端所发送的数据  
                socket.receive(packet); 
                String result = new String(packet.getData(),packet.getOffset(),packet.getLength()); 
                System.out.println("result--->" + result); 
            } catch (Exception e) { 
                // TODO Auto-generated catch block  
                e.printStackTrace(); 
            } 
        } 
    }

Client项目

使用TCP协议

==>TCPClient.java

[java] view plaincopyprint?
package mars; 
 
import java.io.FileInputStream; 
import java.io.InputStream; 
import java.io.OutputStream; 
import java.io.OutputStreamWriter; 
import java.io.Writer; 
import java.net.Socket; 
 
public class TCPClient { 
    public static void main(String[] args) { 
        try { 
            //创建一个Socket对象，指定服务器端的IP地址和端口号  
            Socket socket = new Socket("192.168.1.104",4567); 
            //使用InputStream读取硬盘上的文件  
            InputStream inputStream = new FileInputStream("f://file/words.txt"); 
            //从Socket当中得到OutputStream  
            OutputStream outputStream = socket.getOutputStream(); 
            byte buffer [] = new byte[4*1024]; 
            int temp = 0 ; 
            //将InputStream当中的数据取出，并写入到OutputStream当中  
            while((temp = inputStream.read(buffer)) != -1){ 
                outputStream.write(buffer, 0, temp); 
            } 
            outputStream.flush(); 
        } catch (Exception e) { 
            // TODO Auto-generated catch block  
            e.printStackTrace(); 
        } 
<STRONG><SPAN style="FONT-FAMILY: KaiTi_GB2312; FONT-SIZE: 18px">   }</SPAN></STRONG> 

package mars;

import java.io.FileInputStream;
import java.io.InputStream;
import java.io.OutputStream;
import java.io.OutputStreamWriter;
import java.io.Writer;
import java.net.Socket;

public class TCPClient {
public static void main(String[] args) {
try {
//创建一个Socket对象，指定服务器端的IP地址和端口号
Socket socket = new Socket("192.168.1.104",4567);
//使用InputStream读取硬盘上的文件
InputStream inputStream = new FileInputStream("f://file/words.txt");
//从Socket当中得到OutputStream
OutputStream outputStream = socket.getOutputStream();
byte buffer [] = new byte[4*1024];
int temp = 0 ;
//将InputStream当中的数据取出，并写入到OutputStream当中
while((temp = inputStream.read(buffer)) != -1){
outputStream.write(buffer, 0, temp);
}
outputStream.flush();
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
使用UDP协议

==>UDPClient.java

[java] view plaincopyprint?
package mars; 
 
import java.net.DatagramPacket; 
import java.net.DatagramSocket; 
import java.net.InetAddress; 
 
public class UDPClient { 
    public static void main(String[] args) { 
        try { 
            //首先创建一个DatagramSocket对象  
            DatagramSocket socket = new DatagramSocket(4567); 
            //创建一个InetAddree  
            InetAddress serverAddress = InetAddress.getByName("183.30.189.14"); 
            String str = "hello"; 
            byte data [] = str.getBytes(); 
            //创建一个DatagramPacket对象，并指定要讲这个数据包发送到网络当中的哪个地址，以及端口号  
            DatagramPacket packet = new DatagramPacket(data,data.length,serverAddress,4567); 
            //调用socket对象的send方法，发送数据  
            socket.send(packet); 
        } catch (Exception e) { 
            // TODO Auto-generated catch block  
            e.printStackTrace(); 
        } 
    } 
}
