Implement all the method bodies of the provided Selector class using JAVA

Hint: Refer to the following starter code and handout examples

Problem Overview This assignment focuses on implementing the methods of a class much like java.util.Arrays. The Selector.java file defines a class with static methods designed to provide useful functionality on arrays. 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 are discussing in lecture - systematic, disciplined development and test-based verification. The Selector class You must correctly implement all the method bodies of the provided Selector class. Your implementation must adhere cractly to the API of the Selector class, as described in the provided source code comments and as described below. public final class Selectorf public static int min(intl a) public static int max(intO0 a) public static int kmin(int a, int k) public static int kmax(intl a, int k) public static intl] range (int a, int low, int high) public static int ceiling(intl] a, int key) public static int floor (intl) a, int key The nin method.1 This method selects the minimum value from a given array. If the array is null or has zero length, this method throws an IllegalArgument Exception. The array is not changed by this method. all 2, 8, 7, 3, 4] 5, 9, 1, 7,3 8, 7, 6, 5,4 2, 8, 8, 7, 3, 3, 4 min(a) 2 method This method selects the maximum value from a given array. If the array is null or has zero length, this method throws an IllegalArgumentException. The array is not changed by this method
