Set Intersector Assignment

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>

accept(friendIds)

currentIntersection()

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

Client

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

Testing

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