With respect to the following two different definitions of sets, what are the differences:
Set<Integer> intset = new Hashset<Integer>();
Set<Integer> intset = new Set<Integer>();
Thanks.
You can’t declare new Set its an interface. All of those(Set, Map, List) are interfaces the java.collections package. They are not directly instantiable, but require that implementations(HashSet, ArrayList, Hashmap) be supplied in the right hand side of the assignment operation.
