- Goal 1: Update the Fractions Class Here we will overload two functions that will used by the Recipe class later: multipliedBy, dividedBy Previously, these functions took a Fraction object as a parameter. Now ADD an implementation that takes an integer as a parameter. The functionality remains the same: Instead of multiplying/dividing the current object with another Fraction, it multiplies/divides with an integer (affecting numerator/denominator of the returned object). For example; a fraction 2/3 when multiplied by 4 becomes 8/3. Similarly, a fraction 2/3 when divided by 4 becomes 1/6. Goal 2: Update the Recipe Class The Recipe constructors so far did not specify how many servings the recipe is for. We will now add a private member variable of type int to denote the serving size and initialize it to 1. This means all recipes are initially constructed for a single serving. Update the overloaded extraction operator (<<) to include the serving size (see sample output below for an…Lab 10 Using an interface to share methods It is often the case that two or more classes share a common set of methods. For programming purposes we might wish to treat the objects of those classes in a similar way by invoking some of their common routines.For example, the Dog and Cat classes listed below agree on the void method speak. Because Dog and Cat objects have the ability to “speak,” it is natural to think of putting both types of objects in an ArrayList and invoking speak on every object in the list. Is this possible? Certainly we could create an ArrayList of Dog that would hold all the Dog objects, but can we then add a Cat object to an ArrayList of Dog?Try running the main program below as it is written. Run it a second time after uncommenting the line that instantiates a Cat object and tries to add it to the ArrayList. import java.util.*;public class AnimalRunner{ public static void main(String[] args) { ArrayList<Dog> dogcatList = new ArrayList<Dog>();…The play method in the Player class of the craps game plays an entire game without interaction with the user. Revise the Player class so that its user can make individual rolls of the dice and view the results after each roll. The Player class no longer accumulates a list of rolls, but saves the string representation of each roll after it is made. Add new methods rollDice, getNumberOfRolls, isWinner, and isLoser to the Player class. The last three methods allow the user to obtain the number of rolls and to determine whether there is a winner or a loser. The last two methods are associated with new Boolean instance variables (winner and loser respectively). Two other instance variables track the number of rolls and the string representation of the most recent roll (rollsCount and roll). Another instance variable (atStartup) tracks whether or not the first roll has occurred. At instantiation, the roll, rollsCount, atStartup, winner, and loser variables are set to their appropriate…
- create a driver program, CarTestDriver that uses a Garage object to store Cars. The Garage object is an instantiation of a Garage class that contains “parking”, an array of Car types. You must use a Car[] not an ArrayList<Car> for the “parking” in the garage. I suggest setting up the Car class with a default constructor that generates random values to create each new Car object. The rules for driving the cars from the garage are: The size of the garage is specified by the user. The user may only use cars from the garage A Car is removed from the Garage when a user retrieves a Car from the Garage. The Car is returned to the Garage, after it is driven if it does not run out of fuel. The user interacts with the Car object after the Car object is retrieved from the garage. The program should not fail due to a user selection. A car may only be refueled when the user selects the Car for use, prior to being removed from the Garage The user may select to drive any car that is currently…Problem 3: In classroom, we implemented MyStack by including an ArrayList as private data field of the class (using composition). In this problem, we will use another way to implement the stack class. Define a new MyStack class that extends ArrayList. Draw the UML diagram for the classes and then implement MyStack. Write a test program that prompts the user to enter five strings and displays them in reverse order. (1) Your UML diagram: (3)Part 2: Sorting the WorkOrders via dates Another error that will still be showing is that there is not Comparable/compareTo() method setup on the WorkOrder class file. That is something you need to fix and code. Implement the use of the Comparable interface and add the compareTo() method to the WorkOrder class. The compareTo() method will take a little work here. We are going to compare via the date of the work order. The dates of the WorkOrder are saved in a MM-DD-YYYY format. There is a dash '-' in between each part of the date. You will need to split both the current object's date and the date sent through the compareTo() parameters. You will have three things to compare against. You first need to check the year. If the years are the same value then you need to go another step to check the months, otherwise you compare them with less than or greater than and return the corresponding value. If you have to check the months it would be the same for years. If the months are the same you…
- Complete the Kennel class by implementing the following methods: addDog(Dog dog) findYoungestDog() method, which returns the Dog object with the lowest age in the kennel. Assume that no two dogs have the same age. Given classes: Class LabProgram contains the main method for testing the program. Class Kennel represents a kennel, which contains an array of Dog objects as a dog list. (Type your code in here.) Class Dog represents a dog, which has three fields: name, breed, and age. (Hint: getAge() returns a dog's age.) For testing purposes, different dog values will be used. Ex. For the following dogs: Rex Labrador 3.5 Fido Healer 2.0 Snoopy Beagle 3.2 Benji Spaniel 3.9 the output is: Youngest Dog: Fido (Healer) (Age: 2.0)Goal 1: Update the Fractions Class Here we will overload two functions that will used by the Recipe class later: multipliedBy, dividedBy Previously, these functions took a Fraction object as a parameter. Now ADD an implementation that takes an integer as a parameter. The functionality remains the same: Instead of multiplying/dividing the current object with another Fraction, it multiplies/divides with an integer (affecting numerator/denominator of the returned object). For example; a fraction 2/3 when multiplied by 4 becomes 8/3. Similarly, a fraction 2/3 when divided by 4 becomes 1/6. Goal 2: Update the Recipe Class Now add a private member variable of type int to denote the serving size and initialize it to 1. This means all recipes are initially constructed for a single serving. Update the overloaded extraction operator (<<) to include the serving size (sample output below for an example of formatting) . New Member functions to the Recipe Class: 1. Add four member functions…Use the ArrayList class Add and remove objects from an ArrayList Protect from index errors when removing Practice with input loop Details: This homework is for you to get practice adding and removing objects from an ArrayList. The Voter class was used to create instances of Voters which held their name and a voter identification number as instance variables, and the number of instances created as a static variable. This was the class diagram: The constructor takes a string, passed to the parameter n, which is the name of the voter and which should be assigned to the name instance variable. Every time a new voter is created, the static variable nVoters should be incremented. Also, every time a new voter is created, a new voterID should be constructed by concatenating the string “HI” with the value of nVoters and the length of the name. For example, if the second voter is named “Clark Kent”, then the voterID should be “HI210” because 2 is the value of nVoters and 10 is the number…
- Add the function min as an abstract function to the class arrayListType to return the smallest element of the list.

These are the guides: arrayListType.h arrayListTypeImp.cpp: main.cpp unorderedArraryListType.h unorderedArrayListTypeImp.cpp I am needing these in order to pass the assignment in Cengage Mindtap, please help with codes for each one if possible.Through java, have The Delicious class – fields and constructor The class must define and initialise a field of an appropriate collection class to store Chicken objects. There must be no pre-defined limit on the number of Chiciken objects it can store.The Delicious class – basic methodsThe Delicious class must:• Define a method called addChicken that takes a Chicken object as a parameter and adds it to the ArrayList field. Note that this method must not create a Chicken object. Instead, a Chicken object must be passed into it as a parameter value.• Define a method called getNumberOfChickens that returns the number of Chicken objects in the ArrayList.• Define another method also called getNumberOfChickens. This one takes a single parameter of type int representing a price per Kilogram and returns the number of Chicken objects in the collection whose pricePerKilo is less than or equal to the value of the parameter.• Define a method called list that prints out, via System.out, the details…In Kotlin, use this Employee class Use this Employee class data class Employee(val name: String, val wage: Double, val hours: Double) and this list of Employees: val l: List = listOf(Employee("Bob", 34.33, 42.0), Employee ("Cathy", 27.33, 15.25), Employee("Carlos", 46.99, 38.75), Employee("Tomas", 49.66,28.45), Employee("Xavier", 34.56, 11.5)) Write a function called formatPaycheck that takes a Pair and returns a String. formatPaycheck should use the two parts of the Pair to put together and return a String like this, with the paycheck amount shown to two digits past the decimal point: Pay to the order of Cathy $359.47 Use raise() to raise all the Employees' pay by 15%. Then use map with the payroll and formatPaycheck functions to get a list of the paychecks in the format shown above. Print the result. The output should look like this: [Pay to the order of Bob $1077.79, Pay to the order of Cathy $359.47, Pay to the order of Carlos $1361.09, Pay to the order of Tomas $1056.09,…
