  2.         Read byte array using ByteArrayInputStream Example
  3.         This example shows how to use ByteArrayInputStream object created
  4.         from array of bytes.
  5.        
  6.         Mehod of this class can be called even after calling the close method
  7.         without causing the IOException. Closing ByteArrayInputStream has
  8.         no effect.
