java网络编程的java.net.SocketException: Connection reset异常

一开始学Stream时没注意过write的flush()方法，今天在学网络编程时，注意到了

服务器端：

import java.net.*;
import java.io.*;
public class  Client
{
	public static void main(String[] args) throws Exception 
	{
		Socket socket = new Socket("localhost",8888);
		BufferedOutputStream  out = new BufferedOutputStream(socket.getOutputStream());
		byte[] buff = new byte[2048];
		for(int i = 0 ; i < 2048 ; i ++){
			buff[i] = 'a';
		}
		out.write(buff);
		out.flush();
		out.close();
		socket.close();
	 	System.out.println("Send Over!");
	}
}

客户端：

import java.net.*;
import java.io.*;
public class  Client
{
	public static void main(String[] args) throws Exception 
	{
		Socket socket = new Socket("localhost",8888);
		BufferedOutputStream  out = new BufferedOutputStream(socket.getOutputStream());
		byte[] buff = new byte[2048];
		for(int i = 0 ; i < 2048 ; i ++){
			buff[i] = 'a';
		}
		out.write(buff);
		out.flush();
		out.close();
		socket.close();
	 	System.out.println("Send Over!");
	}
}

当客户端缺少flush语句并且没有关闭close时
