Which type of statment is used to throw an exception?

Modify 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. Use exception-handling techniques for the code verification and display the following message: Enter a talent type or Z to quit >> x x is not a valid code and for valid codes: Enter a talent type or Z to quit >> S Contestants with talent…

This is the question - Write an application that displays a series of at least eight student ID numbers (that you have stored in an array) and asks the user to enter a test letter grade for the student. Create an Exception class named GradeException that contains a static public array of valid grade letters (A, B, C, D, F, and I) that you can use to determine whether a grade entered from the application is valid. In your application, throw a GradeException if the user does not enter a valid letter grade. Catch the GradeException, and then display the message Invalid grade. In addition, store an I (for Incomplete) for any student for whom an exception is caught. At the end of the application, display all the student IDs and grades. Code I was given, I will attach a screenshot of the errors-  public class GradeException extends Exception {     public GradeException(String string) {     } }   import java.util.*; public class TestGrade {    public static void main(String args[]) throws…
