[ILUG] OT: Java Need Advice

[Gareth Eason]

	Hi,

	I'm not sure I completely understand the question but maybe I can point you
in the right direction.

	Arrays are (typically) useful for grouping lots of the *same* data type
together. So I can have an array of ints, or an array of strings, or an array
of characters.

	It sounds like you want to collect and store a number of different data types
(string, char, int, double, float, whatever) in one, easy to use object. I use
the word object deliberately :)

	Consider thinking about creating a class (the template for creating an
object) and putting your various datatypes in there, then instantiating an
object of that class for each time you want to ask and store the results of
the query. So in pseudo code:

class Answers {
   name   : string,
   age    : int,
   weight : float,
   height : double
}

	Then when you're capturing data from the questions you can create a new
object from class Answers and store your data in there. This also allows you
to create an array of Answers objects and store the responses from a bunch of
different question asking sessions :)

	Hope that helps.

	Best regards,
	-->Gar
