Java--常用类

1.  BufferedInputStream inputStream = new BufferedInputStream(socket.getInputStream());
           ByteArrayOutputStream stream=new ByteArrayOutputStream();
           byte[] buff=new byte[1024];
           int readLine=0;
           while ((readLine=inputStream.read(buff))!=-1){
               stream.write(buff, 0, readLine);
           }

   1. 　ByteArrayOutputStream ：是一个缓存流，我们可以将读取的流都放在里面，进行统一的处理，不用边读边写了。
