Java
ArrayLists can only be filled with reference type data, so you cannot fill them with primitive type data. How can you work around this with integers? (How can you have an ArrayList filled with integers?)
please use the name, phonenumber and phonebookentry to build this.
The three parallel arrays are gone — replaced with a single array of type PhonebookEntry.
You should be reading in the entries using the read method of your PhonebookEntry class (which in turn uses the read methods of the Name and PhoneNumber classes).
Use the equals methods of the Name and PhoneNumber classes in your lookup and reverseLookup methods.
Use the toString methods to print out information.
Make 100 the capacity of your Phonebook array
Throw an exception (of class Exception) if the capacity of the Phonebook array is exceeded.
Place a try/catch around your entire main and catch both FileNotFoundExceptions and Exceptions (remember, the order of appearance of the exception types in the catch blocks can make a difference).
Do not use
BufferedReader while(true)
breaks
The name of your application class should be Phonebook. Also, you should submit ALL your classes (i.e., Name, Strip off public from all your class…
[How can you create this in Java, I need help in understanding how to make this work and how it can be created. Please.]
Create a Deque class based on the discussion of deques in this chapter. It should include insertLeft(), insertRight(), deleteLeft(), deleteRight(), isEmpty() and isFull() methods. It will need to support wrapping around at the end of the arrays as queues do.
After you have created the Deque class, write a Stack class based on the Deque class(Use deque class methods). This Stack class should have the same methods and capabilities as the Stack we implemented in class.
Write a main class that tests both Deque and Stack classes.

- Complete the Course class by implementing the printRoster() method, which outputs a list of all students enrolled in a course and also the total number of students in the course. Given classes: Class Course represents a course, which contains an ArrayList of Student objects as a course roster. (Type your code in here) Class Student represents a classroom student, which has three fields: first name, last name, and GPA. (Hint: toString() returns a String representation of the Student object.) Ex: If the following students and their GPA values are added to a course: Henry Cabot with 3.5 GPABrenda Stern with 2.0 GPAJane Flynn with 3.9 GPALynda Robison with 3.2 GPA then the program output is: Henry Cabot (GPA: 3.5) Brenda Stern (GPA: 2.0) Jane Flynn (GPA: 3.9) Lynda Robison (GPA: 3.2) Students: 4 course.java import java.util.ArrayList; // Class representing a studentpublic class Course { private ArrayList<Student> roster; // Collection of Student objects public Course() {…arrow_forwardCan you implement an interface in your class? A solution is placed in the "solution" section to help you, but we would suggest you try to solve it on your own first. Problem Statement# You are given an interface Addition which contains a method signature int add(int num1, int num2). You need to write a class called Calculator which implements the Addition interface. The add(int, int) method takes two integers and returns their sum. Input# Calls the add(int, int) method by passing num1 and num2. Output# Returns the addition of num1 and num2.arrow_forwardPlease use java. Show the steps with pictures. In this assignment, you will implement a class calledArrayAndArrayList. 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 A rrayAndArrayList 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.

- Java : OverviewYou must write a class with which we can generate user identities for employees in a company. The purpose is for you to learn how to use arrays and ArrayList to store multiple values of the same type. TaskIn many workplaces, employees are assigned a username to be able to log in to their computers. One method of generating these usernames is to take the first three letters of the first name and the first three letters of the last name and let them together form the username. A person with the name Sven Andersson then gets the username sveand (only lowercase letters). Your task is to write a class named Usernames that should contain a static method named create, which creates a username as above. The method should take an array of type String as an argument, and return an ArrayList containing a string for each generated username.
