PLease use java In this assignment, you will implement a class called ArrayAndArrayList. This class includes some interesting methods for working with Arrays and ArrayLists. For example, the ArrayAndArrayList class has a “findMax” method which finds and returns the max number in a given array. For a defined array: int[] array = {1, 3, 5, 7, 9}, calling findMax(array) will return 9. There are 4 methods that need to be implemented in the ArrayAndArrayList class: ● howMany(int[] array, int element) - Counts the number of occurrences of the given element in the given array. ● findMax(int[] array) - Finds the max number in the given array. ● maxArray(int[] array) - Keeps track of every occurrence of the max number in the given array. ● swapZero(int[] array) - Puts all of the zeros in the given array, at the end of the given array. Each method has been defined for you, but without the code. See the javadoc for each method for instructions on what the method is supposed to do and how to write the code. It should be clear enough. In some cases, we have provided hints and example method calls to help you get started. For example, we have defined a “howMany” method for you (see below) which counts and returns the number of occurrences of a given element in a given array. For now, the method returns a 0 value as a placeholder. Read the javadoc, which explains what the method is supposed to do. Then write your code where it says “// TODO” to implement the method. You’ll do this for each method in the program. /** * Counts the number of occurrences of the given element in the given array. * @param array to search * @param element to search for * @return number of times element is in array */ public int howMany(int[] array, int element) { // TODO Implement method return 0; } In addition, you will write unit tests to test your method implementations. Each unit test method has been defined for you, including some test cases. First make sure you pass all of the provided tests, then write additional and distinct test cases for each unit test method. For example, we have defined a “testHowMany” method for you (see below) which tests the “howMany” 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. /** * Test howMany method in ArrayAndArrayList. */ @Test void testHowMany() { // element in the array int[] array = {1, 3, 5, 7, 9, 1, 2, 3, 4, 5}; assertEquals(2, this.myArrayAndArrayList.howMany(array, 1)); // TODO write at least 3 additional test cases } You have been provided with ArrayAndArrayList.java and ArrayAndArrayListTest.java. To complete the assignment, implement the methods in ArrayAndArrayList.java, making sure you pass all the tests in ArrayAndArrayListTest.java. Then write at least 3 additional and distinct test cases for each unit test method in ArrayAndArrayListTest.java. Do not modify the name of the methods in ArrayAndArrayList.java or the automated testing will not recognize it. You will submit two files for this assignment: ArrayAndArrayList.java and ArrayAndArrayListTest.java. Make sure your program and the unit testing files run without errors!

● howMany(int[] array, int element) - Counts the number of occurrences of the given
element in the given array.
● findMax(int[] array) - Finds the max number in the given array.
● maxArray(int[] array) - Keeps track of every occurrence of the max number in the given
array.
● swapZero(int[] array) - Puts all of the zeros in the given array, at the end of the given
array.
