Write a program that calculates the area of some simple figures (i.e. a square and a rectangle). One function per figure. Check if the function arguments are greater than 0 – if they aren't, throw an exception. This program should use your own exceptions to communicate with a higher-level code. Add some attribute in your exception to pass a message to the user. Some boilerplate code is included below.

- Write a Month class that holds information about the month. Write exception classes for the following error conditions:• A number less than 1 or greater than 12 is given for the month number.• An invalid string is given for the name of the month.Modify the Month class so that it throws the appropriate exception when either of these errors occurs. Demonstrate the classes in a program.Java Foundations: Please provide a basic exception program. Do not use input, output. Write the Java code for the following: Write the InvalidGradeException class that will be used below Write the Java program that reads an integer grade from a user and checks that it is valid (between 0 and 100). If it is invalid an InvalidGradeException will be thrown, stating what the invalid grade is. This will be caught in the main( ) method which will write a message about the invalid grade.

- Java Foundations: Please provide a basic exception code. Do not use input, output. Please provide code and explain. Thank you. Write the Java code for the following: Write the InvalidGradeException class that will be used below. Write the Java program that reads an integer grade from a user and checks that it is valid (between 0 and 100). If it is invalid an InvalidGradeException will be thrown, stating what the invalid grade is. This will be caught in the main( ) method which will write a message about the invalid grade. If the grade is valid, it is written to the monitor.Please do this in Java! 3. RetailItem Exceptions Programming Challenge 4 of Chapter 6 required you to write a RetailItem class that holds data pertaining to a retail item. Write an exception class that can be instantiated and thrown when a negative number is given for the price. Write another exception class that can be instantiated and thrown when a negative number is given for the units on hand. Demonstrate the exception classes in a program. /** *Description: This program will displays a string without any user interaction *Class: Fall - COSC 1437.81002 *Assignment1: Hello World *Date: 08/15/2011 *@author Zoltan Szabo *@version 0.0.0 */ For each method, you will also be required to create docstring as follows: /** * @param String as args * @return Termination code as int, 0 for normal, anything else is error condition * @throws Nothing is implemented */ Flowcharts/UML and Pseudo code All assignment questions must show design flowchart/UML and/or pseudo code unless otherwise…Java Foundations: Please provide a basic exception program. Please use the variables given in the question. Do not use input, output. Thank you. Write the Java code for the following: Write the Java program that reads an integer grade from a user in main( ), then calls the checkGrade method (passing it the grade that was just read in) to check that it is valid (between 0 and 100). if the checkGrade method determines that the grade is invalid, it generates an InvalidGradeException but does not deal with it. the main( ) method deals with the exception by writing a message about the invalid grade.. If the grade is valid, it is written to the monitor.
- use C++ programing language Write a program that prompts the user to enter a person's date of birth in numeric form such as 8-27-1980. The program then outputs the date of birth in the form: August 27, 1980. Your program must contain at least two exception classes: invalidDay and invalidMonth. If the user enters an invalid value for day, then the program should throw and catch an invalidDay object. Similar conventions for the invalid values of month and year. (Note that your program must handle a leap year.)Modify the MilTime class given under Final exam module. The class should implement the following exceptions: BadHour Throw when an invalid hour (< 0 or > 2359) is passed to the class. BadSeconds Throw when an invalid number of seconds (<0 or > 59) is passed to the class. Demonstrate the class in a driver program. Demo in the main function. the file: // MillTIme.cpp//#include "stdafx.h"#include <iostream>using namespace std;class Time{protected: int hour; int min; int sec;public: Time(int h, int m, int s) { hour = h; min = m; sec = s; } int getHour() { return hour; } int getMin() { return min; } int getSec() { return sec; }}; class MilTime : public Time{private: int milHours; int milSeconds;public: MilTime(int h = 0, int s = 0) : Time(0, 0, s) { if (h < 0 || h > 2359) { cout << "Hours must be in the range 0 - 2359.\n"; milHours = h;…Take a look at the following hypothetical scenario: A function can throw an exception. What are the three possible functions of the function?
- Time Converter 1. Write a program that converts dates from a numerical month-day format to alphabetic month-day format. IE 1/31 or 01/31 would have an output of January 31. 1. User enters the month and day as a single string. It is then converted. (10%) 2. Create 2 exception classes (20%) 1. MonthException thrown for invalid months 2. DayException-thrown for invalid days for the given month 3. You can assume Feb is always 28 days 2. This should run in a for loop and end when a user is done entering dates (70%)Implement function getPercentage that takes two inputs : grade and totalGrade and outputs the gradepercentage as follows: percentage = (grade/total grade)*100 . (Assume a student can not get 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, that is 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 for your getPercentage function.-Modify your parameter constructors to call your set methods. This will cause validation of the parameter.-Create an exception class named TractorException.-Modify your setters to throw TractorException if invalid values are passed in. You may also need to add a throws clause to your parameter constructors. This way we will not have any print methods in our Tractor object defining class-Modify your main method to try and catch exceptions. It should catch TractorExceptions and general Exceptions and display an appropriate message import java.util.*; class TestException { public static void main(String s[]) { Scanner scanner = new Scanner(System.in); boolean valid=false; // validation loop while (!valid) { try { System.out.println("Enter integer:"); int number = scanner.nextInt(); // may throw an exception System.out.println("You entered "+ number); valid=true;…
