JAVA programming language DescriptionYour job is to write your own array list (growable array) that stores elements that are objects of a parentclass or any of its child classes but does not allow any other type of objects to be stored. You will createa general data class and two specific data classes that inherit from that class. You will then write thearray list to hold any objects of the general data class. Finally, you will test your array list using JUnittests to prove that it does what it should.DetailsYour array list must be named DataList. Start with an array with room for 10 elements. Keep all elementscontiguous (no blank places) at the low end of the indices. When the array is full, grow it by doubling thesize. (Do not use any built-in methods to copy the array elements. Write your own code to do this.) Youdo not have to shrink the array when elements are removed. The array list must have the followingpublic methods (listed in UML style where GenClass is your general data…

CLASSES, DYNAMIC ARRAYS AND POINTERS Define a class called textLines that will be used to store a list of lines of text (each line can be specified as a string). Use a dynamic array to store the list. In addition, you should have a private data member that specifies the length of the list. Create a constructor that takes a file name as parameter, and fills up the list with lines from the file. Make sure that you set the dynamic array to expand large enough to hold all the lines from the file. Also, create a constructor that takes an integer parameter that sets the size of an empty list. in C++ Write member functions to: remove and return the last line from the list add a new line onto the end of the list, if there is room for it, otherwise print a message and expand the array empty the entire list return the number of lines still on the list take two lists and return one combined list (with no duplicates) copy constructor to support deep copying remember the destructor!
Computer Science Part 2: Client Program with ArrayList Create a second client program. This program will contain an ArrayList of StudentGrades objects. The program will perform the following tasks: Create an instance of an ArrayList that will store three StudentGrades objects. Each element in the ArrayList represents student grades for a test (assessment). This means that each StudentGrades object stored by the ArrayList element represents the grades achieved by students for a single test. Prompt the user for the number of students in the class. The prompt text is: Enter the number of students in the course: [Keyboard Input] Add three new StudentGrades objects to the ArrayList. The StudentGrades objects should be populated with random values from 0 to 100. Use the enhanced for loop to print each of the StudentGrades objects to the console. Print a line containing the following text: “LAST ELEMENT BEFORE REMOVE:”. Print the value of the final element in the ArrayList under the heading.…
Write a recursive function that returns True if the numerical array passed as input is palindrome, and False otherwise. An array is palidrome if its elements, when flipped, produce an array that is identical to the original one. For example: [1,2,3,2,1] is palindrome [1,2,3,4,3] is not palindrome Fill in the following code skeleton. It is composed of four parts: three base cases and the recursive call. Write code for all the parts. Assume that the input arrays can have any size, and that the elements are always positive integers.
Task on Key index Searching & Sorting Create a KeyIndex class with the following properties : Fields: int [ ] k; Description An array of integers. Note: You may maintain another global variable if needed (but you can’t use more than one). Constructor: KeyIndex(int [ ]a) Description: This constructor takes an array of integers a and populates array k with the element in a as indices into k. Note: make sure the build-up of your array k supports negative and non-distinct integers. Methods: search (int val) Description: This method searches for the value val within the array and returns true if found or false otherwise. sort () Description: This method will return the sorted form of the array that had been passed into the constructor. NOTE: Create a tester class or write tester statements to check whether the methods in your KeyIndex class work properly. You need to submit both the classes as a part of your assignment.…
C# Create class IntegerSet. Each IntegerSet object can hold integers in the range 0–100. The set is represented by an array of bools. Array element a[i] is true if integer i is in the set. Array element a[j] is false if integer j is not in the set. The parameterless constructor initializes the array to the “empty set” (i.e., a set whose array representation contains all false values.) • Provide the following methods: a) Method Union creates a third set that’s the set-theoretic union of two existing sets (i.e., an element of the third set’s array is set to true if that element is true in either or both of the existing sets—otherwise, the element of the third set is set to false). b) Method Intersection creates a third set which is the set-theoretic intersection of two existing sets (i.e., an element of the third set’s array is set to false if that element is false in either or both of the existing sets—otherwise, the element of the third set is set to true). c) Method…
10. Lottery Application Write a Lottery class that simulates a lottery. The class should have an array of five integers named lotteryNumbers. The constructor should use the Random class (from the Java API) to generate a random number in the range of 0 through 9 for each element in the array. The class should also have a method that accepts an array of five integers that represent a per- son's lottery picks. The method is to compare the corresponding elements in the two arrays and return the number of digits that match. For example, the following shows the lotteryNumbers array and the user's array with sample numbers stored in each. There are two matching digits (elements 2 and 4). lotteryNumbers array: User's array: 7 4 4 2 1 3 7 3 In addition, the class should have a method that returns a copy of the lotteryNumbers array. Demonstrate the class in a program that asks the user to enter five numbers. The program should display the number of digits that match the randomly generated…
Language: JAVA Script write a function 'keyValueDuplicates (obj) that takes an object as an argument and returns an array containing all keys that are also values in that object. Examples: obj1 = { orange: "juice", apple: "sauce", sauce: "pan" }; console.log(keyValueDuplicates (obj1)); // ["sauce"] obj2 = { big: "foot", foot: "ball", ball: "boy", boy: "scout"};console.log(keyValueDuplicates(obj2)); // ["foot", "ball", "boy"] obj3 = { pizza: "pie", apple: "pie" pumpkin: "pie"); console.log(keyValueDuplicates (obj3)); // [] *******************************************************************/function keyValueDuplicates (obj) { | // Your code here } /*****DO NOT MODIFY ANYTHING UNDER THIS LINE*********/ try { | module.exports = keyValueDuplicates; } catch (e) { | module.exports = null;}
