Collection interfaces: Collection, List, Set, Map, etc. This second program on stack creates generics stacks storing all ints, doubles, chars and strings. Summary on some java generics presentations/postings. As far as my understanding goes the purpose of Generics in Java is to avoid ClassCastExceptions at runtime and also minimize the crap casts when we get objects from collections. I'm new to java and I got a test today and kind of failed to make it, I was hoping that someone could explain it to me because I still don't get how to use Generic collections.

This is These water down the type-safety guarantee of generics collections to the point where they are no better than non-generic collections. Java 5 enhanced for loop is used to print the elements.
