OK, this I know is probably very simple, but i'd apprechiate the help.

Which of the following statements is NOT true?

Constructors can have parameters
Constructors can return a result
Constructors have the same name as the class they belong to
More than one constructor can be defined in a class

I'm guessing Constructors can return a result, I thought that maybe that you can have more than one constuctor defined is a class wasn't true too but apparently you can?...

Thanks guys.

Constructors can't return a result. Do some reading HERE and HERE for more info on constructors.

as long as the paramater list for each constructor is different, then yes you can have as many as you like, this allows you to instantiate a class with a lot of information or very little.

The constructor itself does not return anything, it is simply the code run when a class is instantiated (eg a copy is made). Nothing is "returned" the copy is simply applied to any variable you had it assigned to.
