- 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…Foundation in java 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..Write the code in java and please don't plagiarize or copy from other sources write it on your own and read the question carefully and write according to it thank you.

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;…
- 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.)A custom exception type is usually defined by: inheriting from the exception class. O inheriting from the try block. a function definition within the except block. a class definition within the finally block.VendingMachine.java Load default template... public static void main (String [] args) { Scanner scnr = new Scanner(System.in); int itemNumber = 0; boolean askForInput = true; while (askForInput) { try { itemNumber = scnr.nextInt(); if ((itemNumber 8)) { throw new Exception("Try again"); } System.out.println("Dispensing item " + itemNumbe askForInput = false; } }
