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. If there are no positive integers in the list, the program should throw a custom exception called "NoPositive IntegersException". Sample Output 1: Enter a list of integers, one integer per line. Enter a negative integer to end the list. -2 There are no positive integers in the list.

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.
If there are no positive integers in the list, the program should throw a custom exception called
"NoPositiveIntegersException".
Sample Output 1:
Enter a list of integers, one integer per line. Enter a negative integer to
end the list.
-2
