OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.
Constructor
The easiest way to think of a constructor in object-oriented programming (OOP) languages is:
True or false: A class may have a constructor with no parameter list, and an overloaded constructor whose parameters all take default arguments.

- True or false: Just as a class can have multiple constructors, it can also have multiple destructors.Remaining Time: 35 minutes, 18 seconds, ¥ Question Completion Status: A class named Account is defined as the following. class Account } private: int id; double balance; public: //A constructor without parameter that creates a default account with id 0, balance 0 Account): /A constructor with the parameter that setting the id and balance Account(int, double), int getId); / return the ID double getBalance() //return the balance void withdraw(double amount) // the amount will be withdrawn void setlID(int), //set the ID void setBalance (double) //set the balance }: Assume that we will create a separate file of implementation of the function definition for the questions a) -b) a) Write a construction function definition with two parameters (ID and balance). b) Write a function definition of the function declaration (void withdraw(double amount):). c) Creates an Account object with an ID (1122) and balance ($20000). Then, write source codes to withdraw $2 MacBooTrue or False It is legal to write a class without any constructors.
- Parent Class: Food Write a parent class called Food. A food is described by a name, the number of grams of sugar (as a whole number), and the number of grams of sodium (as a whole number). Core Class Components For the Food class, write: the complete class header the instance data variables a constructor that sets the instance data variables based on parameters getters and setters; use validity checking on the parameters where appropriate a toString method that returns a text representation of a Food object that includes all three characteristics of the food Class-Specific Method Write a method that calculates what percent of the daily recommended amount of sugar is contained in a food. The daily recommended amount might change, so the method takes in the daily allowance and then calculates the percentage. For example, let's say a food had 6 grams of sugar. If the daily allowance was 24 grams, the percent would be 0.25. For that same food, if the daily allowance was 36 grams, the…T/F: Instance variables are shared by all the instances of the class. T/F: The scope of instance and static variables is the entire class. They can be declared anywhere inside a class. T/F: To declare static variables, constants, and methods, use the static modifier.It's not clear why a class needs a destructor.
- In a class with overloaded constructors, each version of the constructor must have a differentEmployee Class (Medium) Write a class named Employee that has the following member variables: name. A string that holds the employee’s name. idNumber. An int variable that holds the employee’s ID number. department. A string that holds the name of the department where the employee works. position. A string that holds the employee’s job title. The class should have the following constructors: A constructor that accepts the following values as arguments and assigns them to the appropriate member variables: employee’s name, employee’s ID number, department, and position. A constructor that accepts the following values as arguments and assigns them to the appropriate member variables: employee’s name and ID number. The department and position fields should be assigned an empty string (""). A default constructor that assigns empty strings ("") to the name, department, and position member variables, and 0 to the idNumber member variable. Write appropriate mutator functions that…7)Circle Class Write a Circle class that has the following fields: radius: a double PI:a final double initialized with the value 3.14159 The class should have the following methods: Constructor. Accepts the radius of the circles as an argument. Constructor. A no-arg constructor that sets the radius field to 0.0. setRadius. A mutator method for the radius field. getRadius.An accessor method for the radius field. area. Returns the area of the circle, which is calculated as area. Returns the area of the circles, which is calculated as area= PI * radius * radius diameter. Returns the diameter of the cirlce, which is calculated as diameter = radius * 2 circumference. Returns the circumference of the circle, which is calculated as circumference = 2 * PI * radius Write a program that demonstrates the Circle class by asking the user for the circles's radius, creating a Circle object, and then reporting the cirlce's area, diameter, and circumference.
- Child Class: Vegetable Write a child class called Vegetable. A vegetable is described by a name, the number of grams of sugar (as a whole number), the number of grams of sodium (as a whole number), and whether or not the vegetable is a starch. Core Class Components For the Vegetable class, write: the complete class header the instance data variables a constructor that sets the instance data variables based on parameters getters and setters; use instance data variables where appropriate a toString method that returns a text representation of a Vegetable object that includes all four characteristics of the vegetableJavaCircle Class (Easy) Write a Circle class that has the following member variables: radius : a double The class should have the following member functions: Default Constructor: default constructor that sets radius to 0.0. Constructor: accepts the radius of the circle as an argument. setRadius: an mutator function for the radius variable. getRadius: an accessor function for the radius variable. getArea: returns the area of the circle, which is calculated as area = pi * radius * radius getCircumference: returns the circumference of the circle, which is calculated as circumference = 2 * pi * radius Step1: Create a declaration of the class. Step2: Write a program that demonstrates the Circle class by asking the user for the circle’s radius, creating Circle objects, and then reporting the circle’s area, and circumference. You should create at least two circle objects, one sets the radius to 0.0 and one accepts the radius as an…True or False Constructors can accept arguments in the same way as other methods.
