Implement all the method bodies using JAVA.

Collection Selector Problem Overview This assignment focuses on implementing the methods of a class much like java.util.collections. The Selector java file defines a class with static methods that implement polymorphic algorithms that operate on and/or return Collections. Each method of Selector is very clearly specified, is independent of the other methods in the class, and is designed to provide relatively simple functionality. So, this is a great context for practicing what we've been discussing in lecture - generalized programming and test-based verification The Selector class You must correctly implement all the method bodies of the provided Selector class. Your implementation must adhere eractly to the API of the Selector class, as described in the provided source code comments and as described below. public class Selector ( public static T min (Collection T max (Collection c, Comparator comp) public static T kmin(Collection c, int k, Comparatort> comp) public static T kmax (CollectioncT> c, int k, Comparator comp) public static T CollectionT range (Collection comp) public static T ceiling(Collection c, T key, ComparatorT> comp) public static T floor (CollectionT> c,T key, Comparator comp) The sections that follow provide details of each method's behavior as well as specific examples. The min method. This method selects the minimum value from a given collection, as defined by a given comparator. If either the collection or comparator is null, this method throws an IllegalArgument Exception. If the collection is empty, the method throws a NoSuchElement Exception. The collection must not be changed by this method. Examples T min(c, comp) comp Integer Integer Integer (String, Integer) [(A,5), (B,4), (C,3), (D,2), (E, 1)] ascending by String field (A.5) (String, Integer) I(A,5), (B,4), (C,3), (D,2), (E, 1)] ascending by Integer feld (E,1) [2, 8, 7, 3, 4] [8, 7, 6, 5, 4 ascending order descending order ascending order 9
