/*
	Read partial byte array using ByteArrayInputStream Example
	This example shows how to create ByteArrayInputStream from
	partial array of bytes using offset and legth arguments of 
	ByteArrayInputStream constructor.
 
	Method of this class can be called even after calling the close method
	without causing the IOException. Closing ByteArrayInputStream has
	no effect.
