If you are reading a large file, the above program may take some time to complete as it reads only one byte at a time. By default, the internal buffer size is 8KB but we can specify a custom buffer size at the time of initialization.

Here is an example that uses BufferedInputStream with default buffer size to read a binary file:. If your binary file has encoding other the default character encoding of the operating system , or you want to explicitly set an encoding scheme, you have to use the InputStreamReader class instead:. The following example shows how you can use the FileOutputStream class to write data to a binary file in Java:.

It may not be a desirable solution for writing large-sized files. Just like BufferedInputStream , it uses an internal buffer of size 8KB can be customized to store the data and only writes to the disk when the buffer is full.
