Characters

• In Java single characters are represented using
  the data type char. Character constants are
  written as symbols enclosed in single quotes, for
  example, 'a', 'X', and '5'.
• To represent characters in computer, U. S.
  computer manufacturers devised several schemes
  for encoding characters as integers.
• One coding scheme widely used today is ASCII
  (American Standard Code for Information
  Interchange).
