Knowing the Pro's and Cons of Collections

[Arnold Kesselaar]

Is knowing the advantages and constraints of Collections a requirement for SCJP 1.4?

[Corey McGlone]

Well, Arnold, one of the exam objectives regarding the collections framework states:

Make appropriate selection of collection classes/interfaces to suit specified behavior requirements.

So, based on that, I'd say you'd be well off to know some of the benefits and constraints of the different collections. Extreme details probably aren't important, but knowing the basic structure of the collections would definitely be a good idea.

Thanks Corey,
Sarma Lolla recently posted this link which really sums up the benefits and constraints of the collections very well.
