Overview of I/O Streams:

Stream I/O treat all devices in a unified fashion.
The concept of stream I/O extends to keyboard, screen, printers and communication ports.
There are usually several standard stream objects created automatically for you by Java...
    --System.in
    --System.out
    --System.err
To bring in information, a program opens a stream on an information source (a file, memory, a socket) and reads the information sequentially, as shown here:

Similarly, a program can send information to an external destination by opening a stream to a destination and writing the information out sequentially, like this:

No matter where the data is coming from or going to and no matter what its type, the algorithms for sequentially reading and writing data are basically the same:

Reading	Writing
open a stream while more information read information close the stream	open a stream while more information write information close the stream
