In this assignment, you will implement a class called ArrayAndArrayList. This class includessome interesting methods for working with Arrays and ArrayLists.For example, the ArrayAndArrayList class has a “findMax” method which finds and returns themax number in a given array. For a defined array: int[] array = {1, 3, 5, 7, 9}, callingfindMax(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 givenelement 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 givenarray.● swapZero(int[] array) - Puts all of the zeros in the given array, at the end of the givenarray.Each method has been defined for you, but without the code. See the javadoc for each methodfor instructions on what the method is supposed to do and how to write the code. It…
Besides the ArrayList class in Java, do you think there are other classes that are implemented with an array. Name those predefined Java classes, if any.

Notice that we’ve stored the point values of each letter of the alphabet in an integer array named POINTS. For example, A or a is worth 1 point (represented by POINTS[0]), B or b is worth 3 points (represented by POINTS[1]), etc. Notice that we’ve created a prototype for a helper function called compute_score() that takes a string as input and returns an int. Whenever we would like to assign point values to a particular word, we can call this function. Note that this prototype is required for C to know that compute_score() exists later in the program. In main(), the program prompts the two players for their words using the get_string() function. These values are stored inside variables named word1 and word2. In compute_score(), your program should compute, using the POINTS array, and return the score…arrow_forwardPlease Solve the Question in C++ as quickly as you can in 40 minutes. And do the same as asked in the question. Don't use extra things, please. Augment the safearay class in the ARROVER3 program in this chapter so that the user can specify both the upper and lower bound of the array (indexes running from 100 to 200, for example). Have the overloaded subscript operator check the index each time the array is accessed to ensure that it is not out of bounds. You'll need to add a twoargument constructor that specifies the upper and lower bounds. Since we have not yet learned how to allocate memory dynamically, the member data will still be an array that starts at 0 and runs up to 99, but perhaps you can map the indexes for the safearay into different indexes in the real int array. For example, if the client selects a range from 100 to 175, you could map this into the range from arr[0] to arr[75]. Note: Make this class into a template, so the safe array can store any kind of data.…arrow_forward
