Class DataInputStream. A data input stream lets an application read primitive Java data types from an underlying input stream in a machine-independent way. An application uses a data output stream to write data that can later be read by a data input stream.

What is difference between InputStream and FileInputStream?

There is no real difference. FileInputStream extends InputStream , and so you can assign an InputStream object to be a FileInputStream object.
