Something about Socket

Java很强大，socket 通信几句就搞定。

服务端和客户端（最差的代码）：

import java.net.*;
import java.io.*;

class ser
{
	public static void main(String[] aa)
	{
		try{
		ServerSocket sr=new ServerSocket(3000);
		Socket s=sr.accept();
		DataOutputStream o=new DataOutputStream(s.getOutputStream());
		o.writeUTF("test Socket~~~~~~~~~~~~~~");
		}catch(Exception ee){};
		
	}
}

class cli
{
	public static void main(String[] a)
	{
		try{
		Socket c=new Socket("127.0.0.1",3000);
		DataInputStream i=new DataInputStream(c.getInputStream());
		System.out.println(i.readUTF());
		}catch(Exception e){}
	}
}
