Create a Person class that has the properties: name and age. Override toString so that it displays a Person object like this: Where name is the value of the name property and age is the value of the age property. "<Name: name, Age: age>" Person class should have a natural ordering by age in descending order. Create a Main.java file that: Sorts a List of people using Person’s natural ordering. Uses a custom Comparator with an anonymous class that sorts the List of people by name in ascending order. Uses a custom Comparator with a lambda implementation that sorts the list of people by name in descending order.
Reuse your Car class . In a main, build an object of that class, and print out the object using System.out.println(). Notice that this simply reports the memory address of the object in question, and we’d like to do something more useful. To replace (or override) the toString (or equals) function. Now, build a toString function that prints out the make, model, and odometer reading for a vehicle object. public class Car { //instance variables private int odometer; private String make; private String model; //overloading //constructors public Car(int odometer,String make, String model) { this.odometer = odometer; this.make = make; this.model = model; } public Car(String make, String model) { this.make = make; this.model = model; } public Car(String make) { this.make = make; } /* *getter & setter methods */ public int getOdometer() { return odometer; } public void…
Implement the Rectangle class as discussed this week. Use the class declaration below. Your job is to implement the functions. Implement the missing functions yourself. class Rectangle{ private: double width; double length; char *name; void initName(char *); public://constructorsRectangle();Rectangle(double, double, char*);//destructor ~Rectangle(); void setWidth(double); void setLength(double); void setWidth(char *); void setLength(char *); void setName(char *); double getWidth() const; double getLength() const; void printName() const { cout << name; }}; A few notes on the functions: initName(char *): this is a private member function. It should be the only function which dynamically allocates a char array to hold the name. setName(char *): this is a public member function which changes the name of the rectangle to a new name. It does not dynamically allocate memory, it only changes name. Demonstrate your class works…

Write a Java class Student inherited from Person class. Your class must have the following features: Student - major: String + Student() + Student(name: String, id: int, major: String) + getMajor(): String + Override toString() method: you have to return needed data Fields values. Note: major data members can take only CS for Computer Science, CIS for Computer and Information Systems, CPE for Computer Engineering, SE for Software Engineering, and NES for Network Engineering and Security.

Write the definitions of the member functions of the classes arrayListType and unorderedArrayListType that are not given in this chapter. The specific methods that need to be implemented are listed below. Implement the following methods in arrayListType.h: isEmpty isFull listSize maxListSize clearList Copy constructor Implement the following method in unorderedArrayListType.h insertAt Also, write a program (in main.cpp) to test your function.
Q1.(java)Create a generic class with a type parameter that simulates drawing an item at random out of a box. This class couldbe used for simulating a random drawing. For example, the box might contain Strings representing names writtenon a slip of paper, or the box might contain Integers representing a random drawing for a lottery based on numericlottery picks. Create an add method that allows the user of the class to add an object of the specified type along withan isEmpty method that determines whether or not the box is empty. Finally, your class should have a drawItemmethod that randomly selects an object from the box and returns it. If the user attempts to drawn an item out of anempty box, return null. Write a main method that tests your class.
Python Code please Point of Sale Write a program that will manage the point of sale in a store. Build the ItemToPurchase class with the following: Attributes item_name (string) item_price (int) item_quantity (int) Default constructor Initializes item's name = "none", item's price = 0, item's quantity = 0 Method print_item_cost() Example of print_item_cost() output:Bottled Water 10 @ $1 = $10 Extend the ItemToPurchase class to contain a new attribute. item_description (string) - Set to "none" in default constructor Implement the following method for the ItemToPurchase class. print_item_description() - Prints item_description attribute for an ItemToPurchase object. Has an ItemToPurchase parameter. Example of print_item_description() output:Bottled Water: Deer Park, 12 oz. Build the ShoppingCart class with the following data attributes and related methods. Note: Some can be method stubs (empty methods) initially, to be completed in later steps. Parameterized constructor…

(HINT: Look at the member variables).
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. 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 = int(input())dog_breed = input() # TODO: Create generic pet (using pet_name, pet_age) and then call print_info() # TODO: Create dog pet (using dog_name, dog_age, dog_breed) and then call print_info() # TODO: Use my_dog.breed to output the breed of the dog
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).
