Re: Download multiple files in single zip and render for download 2 Months Ago by Sachin_41 what is _response in this? Is this some library? BufferedInputStream versus read() call with byte array as parameter 13 Years Ago by daudiam Using a BufferedInputStream is useful because it cuts down on read system calls. But the same effect can be produced, say in reading a file, if we use FileInputStream's read method that takes a byte array as input. A lot of bytes are read in a single call. Am I right ? Then, why is it that we need to wrap it inside a BufferedInputStream object ? Re: BufferedInputStream versus read() call with byte array as parameter 13 Years Ago by daudiam I assume you are talking of the advantages of using a BufferedInputStream object to wrap a FileInputStream object. But, we can control the read size of the buffer with FileInputStream too (changing the size of the byte array we pass as argument to it). Secondly, I couldn't find the readLine() method in the documentation for BufferedInputStream. Re: BufferedInputStream versus read() call with byte array as parameter 13 Years Ago by daudiam Thanks. You gave 2 main arguments in favour of BufferedInputStream, but : 1. Line endings are still hacked as there is … pass to the read() function. Then, why should be use BufferedInputStream ? We can already have the buffering facility via the proper… Re: BufferedInputStream versus read() call with byte array as parameter 13 Years Ago by masijade Okay, readLine is BufferedReader. In any case, those things I mentioned are using InputStream, BufferedInputStream handles those things for you. Re: BufferedInputStream versus read() call with byte array as parameter 13 Years Ago by masijade Whether you want to do the work yourself, or you want to control the read size of the buffer, or you don't want line endings getting hacked off (if using readLine), etc, etc. Re: BufferedInputStream versus read() call with byte array as parameter 13 Years Ago by ~s.o.s~ > 1. Line endings are still hacked as there is no readLine. Raw input streams shouldn't be used for reading character data anyways so this is a moot point. Byte based streams don't have a notion of "line" hence no "readLine()" method. You make the mistake of assuming streams would always be a character based stream. > We… Re: BufferedInputStream versus read() call with byte array as parameter 13 Years Ago by daudiam Thanks a lot. I got it. One more thing. Buffering helps reduce system calls. So, even when we are reading a small file, we should buffer. But the buffering mechanism must also have its own overhead. Is the overhead so much that we should avoid buffering for small files ? That seems to be the only place where buffering should not be used. Re: BufferedInputStream versus read() call with byte array as parameter 13 Years Ago by ~s.o.s~ It's a good idea to use a Buffered stream/reader even for small files. That way, if you encounter performance problems later on, you can tweak the size of the buffer and improve performance without changing a lot of code (just changing buffer size). But like all performance related things, code tweaked to specific scenarios performs much better … Re: BufferedInputStream versus read() call with byte array as parameter 13 Years Ago by daudiam Thanks a lot.
