The return Or the throw function sometimes returns a random number and throws anither number as an exception. Write a code that will print out the number that the returnorthrow function gives back even if it throws an exception.
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.

- Question 01 - Exceptions Write a Java program that reads a list of integers from the user, and then calculates the average of the positive integers in the list. If there are no positive integers in the list, the program should throw a custom exception called "NoPositiveIntegersException". The program should be implemented as follows: I. II. III. IV. V. Create a custom exception class called "NoPositiveIntegersException" that printout the error message "There are no positive integers in the list" if there are no positive integers in the user entered list. Create another class called "AveragePositiveIntegers" to get the user inputs through the main method. The program should prompt the user to enter a list of integers, one integer per line. The user should indicate the end of the list by entering a negative integer (Ex: -2) Store the user entered positive integers in an ArrayList. Calculate the average of the positive integers and print it to the console, rounded to two decimal places.…arrow_forwardWrite an application that displays a series of at least 10 student ID numbers (that you have stored in an array) and asks the user to enter a test letter grade for the student.
