socket编程的客户端和服务器为什么都要用到Thread.sleep()函数，如果不用这个函数会有什么后果呢？
比方说：clientsideSocketsocket=newSocket("IPaddressofyourserver",12345);OutputStreamout=s...
比方说：
client side
Socket socket=new Socket("IP address of your server ",12345);
OutputStream out=socket.getOutputStream();
out.write(message.getBytes());/*here, message is the information you put in EditText*/
Thread.sleep(200);
InputStream in=socket.getInputStream();
byte[] buffer=new byte[in.available()];
in.read(buffer);
msg=new String(buffer);
server side:
in = client.getInputStream();
Thread.sleep(200);
byte[] buffer=new byte[in.available()];
in.read(buffer);
OutputStream out=client.getOutputStream();
out.write(buffer); 展开

Thread.sleep()是线程的休眠，在服务器与客户端进行交流与数据交换时，会有多个任务在进行，为了保证任务的进行有序，CPU则会对不同的任务有不同的安排，这里就是用到了线程，也就是说，CPU会在线程的休眠期期间执行其他的任务进程，当线程休眠结束时则执行线程相应的操作，从而保证了计算机的各个程序之间的顺利运行，效率大大提高！
