Motivation
Performing the set intersection required by the Mutual Friends exercise can be a bit tricky. This group warmup will familiarize everyone with the provided SetIntersector<E> class.
Code To Use
SetIntersector<E>
class SetIntersector<E>
Code To Implement
| class: | Intersections.java |  |
| methods: | intersectionOf | |
| package: | setintersector.group | |
| source folder: | student/src/main/java |
method: public static <E> Set<E> intersectionOf(Set<E> first, Set<E>... rest) 
(sequential implementation only)
Note: You do not have to implement the logic of set intersection at all, that is all done by the SetIntersector<>() given to you in the imports.
Note: the "rest" parameter leverages the varargs feature. You may treat this parameter as an Set<E>[].
Client
| class: | IntersectionClient.java | DEMO: |
| methods: | main | |
| package: | setintersector.client | |
| source folder: | src/main/java |
Testing
| class: | _IntersectionTestSuite.java |  |
| package: | setintersector.group | |
| source folder: | testing/src/test/java |
