Creating my class Generic.

[ellie spring]

hi,

I've created a class as generic type. Lets say Cart class.
And i declared it to only accept Item objects.

How can i make my class object as iteratable.
Because i want it to be able to be used inside the enhanced for loop.

thanks in advance.

Make the class implement Iterable<Item>, and give it an iterator() method that returns an Iterator<Item>.

Thanks for the reply.

I want to know also the advantage and disadvantage of making my class as generic.
And also when to use it.

thanks.
