The following documentation might be helpful. Collection ArrayList HashSet HashMap Iterator You should take full advantage of the functionality provided by the collection classes to make your solutions as concise and efficient as possible. For example, the Collection interface provides an addAll method that makes it possible to add all of the elements of one collection to another using a single method call. Where appropriate, you should use that method rather than creating a loop that repeatedly calls the add method. Your solutions for these exercises must satisfy the following requirements: You may not use indexed for loops. Use only for-each loops or iterators, as appropriate. None of your methods may include nested loops. Nested loops generally take a long time to iterate over large collections. (You will look at this more formally in CS 240).
