Exception:
- • It is nothing but an undesirable or unexpected event that occurs at run time which interrupts the normal flow of the
program ’s commands. - • Exception handling is a
mechanism that handle runtime errors like “ClassNotFoundException”, “SQLException”, and so on. - • An advantage of exception handling is to maintain a flow of the program.
- • An exception can be handled using “try” and “catch” block.

- How can the default error message be shown whenever an exception is thrown?arrow_forwardModify the GreenvilleRevenue program created in Chapter 10, Case Study 1 so that it performs the following tasks: The program prompts the user for the number of contestants in this year’s competition; the number must be between 0 and 30. Use exception-handling techniques to ensure a valid value and display the error message:Number must be between 0 and 30 The program prompts the user for talent codes. Use exception-handling techniques to ensure a valid code and update the displayed message to the following message:x is not a valid talent code. Assigned as Invalid.where x was the invalid code entered into the console. After data entry is complete, the program prompts the user for codes so the user can view lists of appropriate contestants.

- 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…arrow_forwardIn the event of an exception being thrown, how can the default error message be displayed?arrow_forwardpython Write a program that calculates an adult's fat-burning heart rate, which is 70% of 220 minus the person's age.

If the age entered is not in this range, raise a ValueError exception in get_age() with the message "Invalid age." Handle the exception in __main__ and print the ValueError message along with "Could not calculate heart rate info."
