File copy using Buffered streams. This program copies the file named file1.txt to another file named file1_copy.txt using BufferedInputStream and BufferedOutputStream classes. The program creates a buffered input stream with the source file and a buffered output stream with the destination file.
May 07, 2015 · In this post we do a performance comparison between two different mechanisms for reading a file in Java: the first one consists in the construct of chained class BufferedReader, InputStreamReader and FileInputStream and the other one is represented by the simple Scanner class. Let's call them BOS and FOS for short. First of all, BOS wraps another output stream - every byte you write to the BOS will eventually be written to the underlying output stream, which could be a FileOutputStream, a ByteArrayOutputStream, or others. Feb 12, 2020 · In general, BufferedReader comes in handy if we want to read text from any kind of input source whether that be files, sockets, or something else. Simply put, it enables us to minimize the number of I/O operations by reading chunks of characters and storing them in an internal buffer.

The example presented might be simple however it shows the behaviour of the available().
