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 Investigate

SetIntersector<E>

class SetIntersector<E>

accept(friendIds)
currentIntersection()

Code To Implement

class: Intersections.java Java.png
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.svg (sequential implementation only)

Note: the rest parameter leverages the varargs feature. You may treat this parameter as an array of Set<E>s.

Client

class: IntersectionClient.java DEMO: Java.png
methods: setintersector.client
package:
source folder: src//java

Testing

class: _IntersectionTestSuite.java Junit.png
package: setintersector.group
source folder: testing/src/test/java
