[HELP] A "collection" in Java

[liQuorice]

Hello,

I don't know if I'm in the right section but here it goes.

So in Java you have arrays, which have a certain structure so you can return an object stored in that array at the index you like.

But now I'm doing this assignment where we make our own CollectionInterface which stores Indentifiers without any structure.

So now I can't just go: collection[4] = identifier.

Now I was wondering how I could store an input like this: {ball doll monkey} ; into a collection. And also how I could retrieve "doll"?

Yours,

liQuorice

Hi
You can use Object[]. when you want to get certain structure you can use typecasting or another way you have use generic for this aim. but I don't think that it will be good choice for you.

Collections are already part of the standard Java library. You could look at the way it's done there.
