Which statement is false? Select one: O a. The compiler alvways creates a default constructor for a class. O b.If a class has constructors, but none of the public constructors are no- argument constructors, and a program attempts to call a no-argument constructor to initialize an object of he class, a compilation error occurs. O c.A constructor can be called with no arguments only if the class does not have any constructors or if the class has a public no-argument constructor. O d. Java allows other methods of the class besides its constructors to have the same name as the class and to specify return types.

Mark the following statements as true or false. The member variables of a class must be of the same type. (1) The member functions of a class must be public. (2) A class can have more than one constructor. (5) A class can have more than one destructor. (5) Both constructors and destructors can have parameters. (5)
Which of the following applies to destructors? Choose all that apply. A.) A destructor is a function that automatically gets called when an object of its class falls out of scope. B.) If you create a copy constructor, you must also create a copy destructor. C.) A destructor cannot take any parameters. D.) A destructor cannot return a value.
Analyse the following code. public class Test { int x; public Test(String t) { System.out.println("Test"); } public static void main(String[] args) { Test test = new Test(); System.out.println(test.x); } } A. The program has a compile error because you cannot create an object from the class that defines the object. B. The program has a compile error because System.out.println method cannot be invoked from the constructor. C. The program has a compile error because x has not been initialized. D. The program has a compile error because Test does not have a default constructor.

ABC Bank announced a new scheme of reward points for a transaction using an ATM card. Each transaction using the normal card will be provided by giving a reward percentage of the transaction amount as a reward point. If a transaction is made using a premium card and it is for fuel expenses, additional 10 points will be rewarded. Write a program to calculate the total reward points.Strictly adhere to the Object-Oriented specifications given in the problem statement. All class names, member variable names, and function names should be the same as specified in the problem statement.A class VISACard has the following attributes.

The code below demonstrates the Idea of constructor overloading. However, the programmer forgot to add the main function to execute the code. Produce the main function and create three object variables, one for each of the constructors and initialize them. By using the display() method, write the necessary codes to display the output of the each constructor. #include <iostream> using namespace std; class CHELSEA { private: int x,y; public: CHELSEA () //constructor 1 with no arguments { x = y = 0; } CHELSEA(int a) //constructor 2 with one argument { x = y = a; } CHELSEA(int a,int b) //constructor 3 with two argument { x = a; 4 y = b; } void display() { cout << "x = " << x << " and " << "y = " << y << endl; } };

Hello please solve the below in C++. I used the code provide by a Bartleby expert and I was marked down, the feedback was “it doesn't overload the operators as it should” Question Create a class called Rational (separate the files as shown in the chapter) for performing arithmetic with fractions. Write a program to test your class. Use integer variables to represent the private data of the class-the numerator and the denominator. Provide a constructor that enables an object of this class to be initialized when it's declared. The constructor should contain default values in case no initializers are provided and should store the fraction in reduced form. For example, the fraction 2/4 would be stored in the object as 1 in the numerator and 2 in the denominator. Provide public member functions that perform each of the following tasks: Make an overloaded operator of the + symbol for the add method - Adds two Rational numbers. The result should be stored in reduced form. Make an overloaded…
