A subset of the InputStream hierarchy

InputStream {abstract}
    FileInputStream
    FilterInputStream
        BufferedInputStream
        DataInputStream {implements DataInput interface}

Notes

• All classes in the java.io and java.util.zip packages that end with InputStream are members of the InputStream hierarchy.
• The FilterInputStream class is a superclass of all classes that filter binary input streams.

Classes used to connect a binary input stream to a file

DataInputStream	reads data from the stream
	->BufferedInputStream	creates a buffer for the stream
		->FileInputStream	connects the stream to the file

Constructors of these classes

How to connect a binary input stream to a file

DataInputStream in = new DataInputStream(
                     new BufferedInputStream(
                     new FileInputStream(productsFile)));
