begin
  # code that raise an error 
  # or an exception
rescue Exception => e
  # e is an Exception object contains
  # information of the error
  # e.message is the information
  # about why error occurred and
  # which object caused the error,
  # where e.backtrace(Array) holds
  # information about where and

  puts e.message, e.backtrace
