Language: C++ Write a Garage class that has a Car (i.e., object of a second class) that is having troubles with its Motor (i.e., object of a third class). Use a function-level try block in the Garage class constructor to catch an exception (thrown from the Motor class with the string "This motor has problems") when its Car object is initialized. Throw a different exception with the string "The car in this garage has problems with the motor" from the body of the Garage constructor's handler and catch it in the main function.

- in c # i need to Write the program BookExceptionDemo for the Peterman Publishing Company. Create a BookException class that is instantiated when a Book’s price exceeds 10 cents per page and whose constructor requires three arguments for title, price, and number of pages. Create an error message that is passed to the Exception class constructor for the Message property when a Book does not meet the price-to-pages ratio. Next, create a Book class that contains fields for title, author, price, and number of pages. Include properties for each field. Throw a BookException if a client program tries to construct a Book object for which the price is more than 10 cents per page. Finally, using the Book class, create an array of five Books. Prompt the user for values for each Book. To handle any exceptions that are thrown because of improper or invalid data entered by the user, set the Book’s price to the maximum of 10 cents per page. At the end of the program, display all the entered, and…in C# i need to Write the program BookExceptionDemo for the Peterman Publishing Company.

The constructor for the class is declared as: Fraction::Fraction(); Implement an exception handling design in the parameterized constructor to catch zeros in the denominator. Show the new exception class you will need to put in the header (specification) file. Show the definition for your parameterized constructor that throws the exception if the denominator is zero. Finally, show how to use the try-catch statement in the driver program when instatiating a new paramerized Fraction object. You do not need to show entire programs, only the requested lines of source code
- ANSWER IN JAVA Standard Output: Enter·side·length·of·square:Side·length·must·be·greater·than·0.↵ Define the class InvalidSideException, which inherits from the Exception class. Also define a Square class, which has one method variable -- an int describing the side length. The constructor of the Square class should take one argument, an int meant to initialize the side length; however, if the argument is not greater than 0, the constructor should throw an InvalidSideError. The Square class should also have a method getArea(), which returns the area of the square.Create a Driver class with a main method to test your classes. Your program should prompt the user to enter a value for the side length, and then create a Square object with that side length. If the side length is valid, the program should print the area of the square. Otherwise, it should catch the InvalidExceptionError, print "Side length must be greater than 0.", and terminate the program.void foo () { try { throw new Exception1 (); print (" A "); throw new Exception2 (); print (" B "); } catch ( Exception1 e1 ) { print " handler1 "; } print (" C "); throw new Exception2 (); } void main () { try { try { foo (); print (" D "); } catch ( Exception1 e1 ) { print " handler2 "; } print (" E "); } catch ( Exception2 e2 ) { print " handler3 "; } } Write down the output of the program and justify why it is the output. Instead of the “replacement” semantics of exception handling used in modern languages, a very early design of exception handling introduced in the PL/I language uses a “binding” semantics. In particular, the design dynamically tracks a sequence of “catch” blocks that are currently active; a catch block is active whenever the corresponding try block is active. What will be the output of the following program if the language uses the “binding” semantics? Give the reasoning for your answer.Write a C# program StudentGradeDemo that attempts to create several valid and invalid ReportCard objects. Immediately after each instantiation attempt, handle any thrown exceptions by displaying an error message. Create a ReportCard class with four fields for a student name, a numeric midterm grade, a numeric final exam grade, and letter grade. The ReportCard constructor requires values for the name and two numeric grades and determines the letter grade. Upon construction, throw an ArgumentException if the midterm or final exam grade is less than 0 or more than 100. The letter grade is based on the arithmetic average of the midterm and final exams using a grading scale of A for an average of 90 to 100, B for 80 to 90, C for 70 to 80, D for 60 to 70, and F for an average below 60. Display all the data if the instantiation is successful. Use the Main() method to test your code.

- In c++ implement function getPercentage that takes two inputs: grade and total Grade and outputsthe gradepercentage as follows: percentage = (grade/total grade)*100 . (Assume a student can notget a grade above 100%)Define your own exception classes:1. DivideByZeroException as a derived class of Standard Library class runtime_error,that is used to detect division by zero run time error.2. NegativeNumberException as a derived class of Standard Library class logic_error,that is used to detect if the user entered a negative number as a grade.3. InvalidGradeException as a derived class of Standard Library class logic_ error, thatis used to detect if a user entered an invalid input (grade greater than total grade).Use the above exception classes after implementing them to apply exception handling foryour getPercentage function.Complete the following Java program by typing in the missing statements in the space provided. This program inputs a value/s from user, and displays the result of some operation. If the operation generated an exception / error, it is handled by the user defined exception class. The main method in the application class is declared to throw a user-defined exception which will take care of the exception. import // for input from keyboard public class MyExceptionApp { public static void main( ) throws MyDivByZeroException { Scanner kb = System.out.println("Enter two numbers for division : "); double n1 = kb.nextDouble(); double n2 = kb.nextDouble(); try{ if( n2 == 0 ) throw else System.out.println("Answer = " + n1/n2); } catch ( e){ System.out.println("Exception caught : " + e); }…1. If a class declaration does not specify extends and a class name to the right of the new class name, the new class does not extend an existing class. Is it True or False? 2. The catch keywords must be used to handle the exception thrown by try block in some rational manners. True or False? 3. A very important fact to remember is that Java does not support multiple inheritance. True or False?
