/**
  *  ==========================================================================
  *  Scanner1.java: The class Scanner provides support for parsing of primitive
  *  data types (e.g., int, float and double) and strings. A Scanner breaks its
  *  input into tokens, which by default will be delimited by whitespace. The
  *  tokens may then be converted into values of different types using the
  *  various next methods.
  * 
  *  This program demonstrate use of a Scanner for input of text, integers,
  *  and floating-point numbers from the keyboard (i.e., System.in).
