These two are general purpose classes used by the programmer very often to copy file to file. These classes work well with files containing less data of a few thousand bytes as by performance these are very poor.
For larger data, it is preferred to use BufferedInputStream (or BufferedReader) and BufferedOutputStream (or BufferedWriter).

FileInputStream:
============
This stream is used for reading data from the files.
Objects can be created using the keyword new and there are several types of constructors available.

InputStream f = new FileInputStream("C:/java/hello");


FileOutputStream:
==============
FileOutputStream is used to create a file and write data into it.
The stream would create a file, if it doesn't already exist, before opening it for output.


OutputStream f = new FileOutputStream("C:/java/hello")
