Day20 Java Socket使用

Java中Socket的使用

client端

package org.tizen.test;

import java.io.IOException;
import java.io.OutputStream;
import java.net.InetAddress;
import java.net.Socket;
import java.net.SocketTimeoutException;

public class TestSocket {
	public static void main(String []str)
	{
		OutputStream os = null;
		Socket socket = null;
		try {
			//1.创建socket的对象，通过构造器指明服务端的IP地址，以及接收的端口号
			socket = new Socket(InetAddress.getByName("192.168.1.104"),9000);
			//2.getOutputStream发送数据，返回OutputStream
			os = socket.getOutputStream();
			//3.具体的输出过程
			os.write("1111111111  1111111111".getBytes());
		} catch (Exception e) {
			// TODO: handle exception
		}finally
		{ 
			//4.关闭具体的流和socket
			if(os!=null)
			{
				try {
					os.close();
				} catch (IOException e) {
					// TODO Auto-generated catch block
					e.printStackTrace();
				}
			}

			
			if(socket!=null)
			{
				try {
					socket.close();
				} catch (IOException e) {
					// TODO Auto-generated catch block
					e.printStackTrace();
				}
			}
					
		}
		
		
		
	}
}

server端

package org.tizen.test;

import java.io.IOException;
import java.io.InputStream;
import java.net.ServerSocket;
import java.net.Socket;



public class TestTCPIP {
	public static void main(String []str)
	{
		ServerSocket ss = null;
		Socket s = null;
		InputStream is = null;
		try {
			//1. 创建一个SocketServer的对象，通过构造器指明自己的端口
			ss = new ServerSocket(9000);
			//2.调用SocketServer的accept方法，返回一个Socket对象
			s = ss.accept();
			//3.调用Socket对象的getInputStream获得客户端发送过来的流
			is = s.getInputStream();
			byte[] b = new byte[20];
			int len; 
			while((len = is.read(b))!=-1)
			{
				String str1 = new String(b,0,len);
				System.out.println(str1);
			}
		} catch (IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
		
	}
