C++ Question 2 1. Define a class named "BoolVariable" that manages a variable name (string)and a boolean value (true or false). It should not have default constructor.The class must at least provide the following methods:o toString() method that can return a string in the following format:variable-name(variable-boolean-value) such as isSuccessful(true)o containsIgnoreCase() that accepts a search string and it will return true ifits variable name contains that string (case-insensitive) and falseotherwise.Show how this class being used to create objects and call all its methods and showhow they work.2. Define a new exception class named "VarNameException" that must inheritfrom the C+H runtime error class. This class will capture the error case for avariable name when it is empty, only blanks or starting with a number.For example, if the user tries to create with a variable name of ",“Iname", it will generate an exception and this class should capture the reasonand the error value.", or

2. Define a new exception class named "VarNameException" that must inherit from the C++ runtime error class. This class will capture the error case for a variable name when it is empty, only blanks or starting with a number. For example, if the user tries to create with a variable name of “", “ ", or "Iname", it will generate an exception and this class should capture the reason and the error value.

In this exercise, you have to calculate the student's total marks using the concept of Classes Problem Statement# Write a Java class called Student with ● private fields: ○ name(String type) ○ mark1 and mark2 (double type) And methods: ● getMarks(int markNumber), a method which should return mark1 if markNumber equals 1 and mark2 otherwise. ● calcTotal() method should take the two marks entered and return their sum. Also define two constructors: ● A default constructor that takes no parameters and initializes the values to zeros and null. ● A constructor that takes the three variables and sets them as the values of the appropriate fields. Input# Name of the student and the marks obtained in the first and second tests Output# Sum of both marks Sample Input# Student student = new Student("Jack", 60, 70); Sample Output# getMarks(1) => 60 getMarks(2) => 70 calcTotal() => 130.0 Part of solution class Student { // Define private fields here public Student() { // Write…

It should have the following private data members: String size: size of the pizza could be small, medium, or large int numOfToppings: number of toppings could be 1, 2 or 3. double price and should provide the following methods: default constructor (set size to an empty string, numOfTopping and price to 0) non-default constructor Pizza(String s, int n, double p) getters and setters for the three data members method toString()returns a string representing the Pizza object, formatted as: Size: large Toppings: 2 Price: 9.95 method equals (Object obj) to indicate some other object is “equal to” this one public class Pizza { }

_4.1g Write a Java class that would match a string. The class has method match with String as a return type. It accepts two inputs: the phrase/sentence string (text) and the pattern string (word). This method finds the first (or all) instances of the pattern in the text and changes that word in all uppercase and return the new phrase. Method countOccurence accepts a phrase/sentence and a pattern string and returns its number of occurrences. Add a main method that will allow the user to input the phrase/sentence and pattern. Call method match and countOccurence. See test case below. Sample Input: Text string: You will always have my love, my love, for the love I love is as lovely as love itself. Pattern string: love . .
Write a Rational class. Recall a rational number is a rational number, composed of two integers with division indicated. The division is not carried out, it is only indicated, as in 1/2, 2/3, 15/32. You should represent rational numbers using two int values, numerator and denominator. #include <iostream> #include <string> #include <stdlib.h> using namespace std; class rational { public: /* default constructor set the rational number to 0, (i.e., numerator is 0, denominator is 1) */ rational(); /* Set the invoking object's value from user input */ void input(); /* Display invoking object's value in the standard output, in the form of numerator/denominator */ void output() const; //return the invoking object's numerator int get_numerator() const; //return the invoking object's denominator int get_denominator() const; // Set invoking object to be the sum of op1 and op2 void Add(const rational& op1, const rational& op2); // Set the invoking…
Define a new "Exam" class that manages the exam name (string) and its score (integer). For example, an exam can have - "Midterm Exam", 100 - "Final Exam", 50 The class must not provide the default constructor. It must require the exam name and score in order to initialize the Exam object. The class must provide only the following methods (no more and no less): - isPerfect method that returns true if the score is exactly 100 and false otherwise. - isPassing method that returns true if the score is equal or greater than 70 and false otherwise. - toString method must return all the exam information including the result of the exam as a string in the following format: EXAM(<name>) SCORE(<score>) RESULT(Pass/Fail) such asEXAM(Midterm Exam) SCORE(100) RESULT(Pass) EXAM(Final Exam) SCORE(50) RESULT(Fail) "Pass" means the score is greater or equal 70. "Fail" is whenever the score is below 70. - isGreater method that compares with another Exam object and return true if the score…

Write a program to test your class. Complex numbers have the form realPart + imaginaryPart * i where i is Use double variables to represent the private data of the class. 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. Provide public member functions that perform the following tasks: Adding two Complex numbers: The real parts are added together and the imaginary parts are added together.
