Fancy Integer ArrayList (ONLY NEED HELP WITH WRITING TEST CASES)For example, we have defined a “testRemoveInt” method for you (see below) which tests the “remove” method. Pass the tests provided then write additional tests where it says “// TODO”. You’ll do this for each unit test method in the program.import static org.junit.jupiter.api.Assertions.*;import java.util.ArrayList;import org.junit.jupiter.api.Test;class CustomIntegerArrayListTest { @Test void testSpliceIntInt() { CustomIntegerArrayList arr1 = new CustomIntegerArrayList(); arr1.add(2); arr1.add(3); arr1.add(4); arr1.add(5); arr1.add(6); arr1.splice(3, 2); ArrayList<Integer> lst1 = new ArrayList<Integer>(); lst1.add(2); lst1.add(3); lst1.add(4); assertEquals((int) lst1.get(0), (int) arr1.get(0)); assertEquals((int) lst1.get(1), (int) arr1.get(1)); assertEquals((int) lst1.get(2), (int) arr1.get(2)); // TODO write at least 3 additional test cases } @Test void testSpliceIntIntIntArray() { CustomIntegerArrayList arr1 = new CustomIntegerArrayList(); arr1.add(2); arr1.add(3); arr1.add(4); arr1.add(5); arr1.add(6); arr1.splice(3, 1, new int[] { 4, 5 }); ArrayList<Integer> lst1 = new ArrayList<Integer>(); lst1.add(2); lst1.add(3); lst1.add(4); lst1.add(4); lst1.add(5); lst1.add(6); assertEquals(lst1, arr1.getArrayList()); // TODO write at least 3 additional test cases Homework 4: Fancy Integer ArrayListThis assignment is designed to give you practice writing code and applying lessons andtopics for the current module.This homework deals with the following topics:ArrayListsOverloading• Unit TestingThe AssignmentIn this assignment, you will implement a class called Custom IntegerArrayList. This classrepresents a fancy ArrayList that stores integers and supports additional operations notincluded in Java's built-in ArrayList methods.For example, the Custom IntegerArrayList class has a "splice" method which removes aspecified number of elements from the Custom IntegerArrayList, starting at a given index. For aCustomIntegerArrayList that includes: 1, 2, 3, 4, and 5, calling splice(1, 2) will remove 2 itemsstarting at index 1. This will remove 2 and 3 (the 2nd and 3rd items).The CustomIntegerArrayList class has 2 different (overloaded) constructors. (Remember, anoverloaded constructor is a constructor that has the same name, but a different number, type,or sequence of parameters, as another constructor in the class.) Having 2 differentconstructors means you can create an instance of the Custom IntegerArrayList class in 2different ways, depending on which constructor you call. Both constructors have beenimplemented for you. (See below)Internally, the Custom IntegerArrayList class uses a private ArrayList variable named "arr" tostore its integer elements. The "CustomIntegerArrayList()" constructor initializes the ArrayListvariable "arr" as an empty ArrayList and the "CustomIntegerArrayList(ArrayList arr)"constructor initializes the ArrayList variable "arr" with the elements in the given ArrayList.(Again, see below)/*** Fancy ArrayList that stores integers and supports additionaloperations not included in Java's built-in ArrayList methods.*/ public class CustomIntegerArrayList {// instance variables/*** Internal ArrayList of elements.*/private ArrayList arr;// constructors/*** Creates a new empty Custom IntegerArrayList.*/public Custom IntegerArrayList ()}this.arr = new ArrayList ();/*** Creates a new Custom IntegerArrayList with the elements inthe given ArrayList.*@param arr with elements for the Custom IntegerArrayList*/public Custom IntegerArrayList (ArrayList arr) {this.arr = new ArrayList (arr);}There are 8 (mostly overloaded) methods that need to be implemented in theCustomIntegerArrayList class. (Again, an overloaded method is a method that has the samename, but a different number, type, or sequence of parameters, as another method in the sameclass.)getArrayList() - Returns the elements.•get(int index) - Returns the element at the specified index from the elements.add (int element) - Appends the given element to the end of the elements.•add (int index, int element) - Inserts the given element at the specified index.remove(int index) - Removes the element at the specified index.•remove(int num, int element) - Removes the specified number of the given elementfrom all elements.•splice (int index, int num) - Removes the specified number of elements from allelements, starting at the given index.• splice (int index, int num, int[] otherArray) - Removes the specified number of elementsfrom all elements, starting at the given index, and inserts new elements in the givenarray at the given index.
