Start with this class declaration: class Student { int sId; String name; double gpa;} Implement a Comparable and Comparator interface to provide the following three (3) alternative ways of ordering for the Student objects - based on sId (i.e., assume that this is selected as the natural ordering)- based on name, - based on gpa. Next declare a list of five Student objects, initialize them with random values. Test your code by printing out each of the following on separate lines: (original list of students, sorted list of students in ascending sId order, sorted list of students in ascending name order, sorted list of students in ascending gpa order).
Write a checkbook balancing program. The program will read in the following information for all checks that were not cashed as of the last time the user balanced their checkbook: the number of each check the amount of the check whether or not the check has yet been cashed Use a dynamic array with a class base type for the checks. The checkclass should have three member variables: check number check amount whether or not the check's been cashed And don't forget to provide accessors, mutators, and constructors as well as input and output methods.

java program Create a class Term. This class represents a term of a polynomial such as 2x4 where 2 is coefficient and 4 is exponent of the term.Data members:-• int coefficient• int exponentCreate another class Polynomial. The internal representation of a polynomial is an array of Terms. The size of this array should be fixed.Provide a constructor for this class that will set all terms of a polynomial object as zero (where coefficient is 0 and exponent is 0). Provide following functions:• setTerm(int, int) – Setting a term of a polynomial object. Each successive call of this function should set next term of the polynomial object.It should do the following validations:-• Whether the exponent of the term being set is already used.• Whether the array size limit is exceeded.• Whether the exponent is negative.In all the cases it should not set the term and display an appropriate message.• sort() – to arrange the terms in ascending order of exponents.• provide a function to print a polynomial…
The class diagram below shows an Order class that "has a" Customer and zero or more Items. Order class should contain private Customer m_cust; private ArrayList<Item> m_items; public Order(Customer cus t) public void additem(Item i) public String toString() Item class should contain private String m_desc private int m_qty private double m_price public Item(String des c, double price, int qty) public String toString() Customer class should contain private String m_first; private String m_last; public Customer(String first, String last) public String toString() Please create the Order, Customer, and Item classes shown above. I have provided you with a read-only Main class that you can use to test your code. When you have completed the Order, Customer, and Item classes, running the Main program should produce the following output: Order for Smith, Tom Order Items: Greeting Card: 1 at 1.5 Baseball Glove: 1 at 54.0 Notebook: 3 at 2.5 public class Main{ public static void…
The base class Pet has attributes name and age. The derived class Dog inherits attributes from the base class Pet class and includes a breed attribute. Complete the program to: Create a generic pet, and print the pet's information using print_info(). Create a Dog pet, use print_info() to print the dog's information, and add a statement to print the dog's breed attribute. Ex: If the input is: Dobby 2 Kreacher 3 German Schnauzer the output is: Pet Information: Name: Dobby Age: 2 Pet Information: Name: Kreacher Age: 3 Breed: German Schnauzer code to be used: python class Pet: def __init__(self): self.name = '' self.age = 0 def print_info(self): print('Pet Information:') print(' Name:', self.name) print(' Age:', self.age) class Dog(Pet): def __init__(self): Pet.__init__(self) self.breed = '' my_pet = Pet()my_dog = Dog() pet_name = input()pet_age = int(input())dog_name = input()dog_age =…

Write a checkbook balancing program. The program will read in the following information for all checks that were not cashed as of the last time the user balanced their checkbook: the number of each check the amount of the check whether or not the check has yet been cashed Use a dynamic array with a class base type for the checks. The check class should have three member variables: check number check amount whether or not the check's been cashed And don't forget to provide accessors, mutators, and constructors as well as input and output methods. BTW, the amount member variable will be of type Money. Just save this link to the Money class definition — you do not have to design it yourself! (A closer look, however, reveals that it is just a class definition... The definitions for the methods seem to be missing. Bummer...) In addition to all of the checks since the last checkbook update, your program should also read all of the user's deposits, the last balance we reported…
Consider the following class hierarchy: class Animal { ... } class Mammal extends Animal { ... } class Cat extends Mammal { ... } Write a generic method printArray that takes an array of any type and prints each element of the array. If the element is an instance of Animal or its subclass, the method should call the toString method of the object to print its details. Otherwise, the method should simply print the element. Your method should have the following signature: public static <T> void printArray(T[] array)
Following the instructions presented in the Lecture 4.5 and 4.6, complete the class Bag we discussed in the lectures. It should include all the data members, constructors, as well as all the member functions we have discussed. To be more specific, the class should have an interface shown as following: class Bag { private: int items[100]; int itemCount; public: Bag(); int getItemCount(); bool add(int newItem); void display(); bool contains(); bool remove(int a); int getSum(); }; Please complete all the member functions listed above including the default constructor. Then add following member function to the class: getMax() This function returns the largest integer stored in the Bag without changing the position of each integer stored in the Bag. Write a C++ program in a .cpp file (source file) that include above class Bag and perform following tasks: Use function rand() to randomly generate 80 integers between 0 and 99 and put them into an object of the class Bag. Use…

Java Program The assignment requires two classes. Put all classes in the same package. Class Employee Attributes (all private): id: String lastName: String firstName: String salary: int Methods: Parameterized constructor for initializing a new Employee instance Getters for all attributes toString method to display an Employee's attributes (See output of executable below) Executable Class Create an array of at least eight Employee objects. Be sure to use many with identical last names, but don't order them by name in the array. Create an ArrayList from the array. Sort the ArrayList first by last name and then by first name. Using the forEach method and a lambda expression, print all employees alphabetically sorted by name. Create a LinkedList from the ArrayList. Create an iterator capable of cycling both forward and backward through the LinkedList. Iterate forward through the LinkedList without generating any output. Then iterate backwards through the LinkedList to print…
