Java Tutorial - Java Script :
All byte streams are a subclass of either InputStream or OutputStream. These classes are abstract, so you cannot create a stream by creating objects of these classes directly. Instead, you create streams through one of their subclasses, such as the following:
· FileInputStream and FileOutputStream—Byte streams stored in files on disk, CD-ROM, or other storage devices
· DataInputStream and DataOutputStream—A filtered byte stream from which data such as integers and floating-point numbers can be read
InputStream is the superclass of all input streams. File Streams The byte streams you’ll work with most often are likely to be file streams, which are used to exchange data with files on your disk drives, CD ROMs, or other storage devices you can refer to by using a folder path and filename. You can send bytes to a file output stream and receive bytes from a file input stream.
