Answer to Question #234971 in Java | JSP | JSF for Momo

Question

Design a Java application that will allow a user to capture the top students for a module. Allow the
user to enter in the module name, followed by the number of students the user would like to
capture
Continue to capture the results for the number of students entered. Once all the student results
have been captured create a results report.
In the results report display the student results entered, a student count and the average result
obtained.
Make use of a method to get the input from the user, another method to accumulate the student
results, a method to determine the average result and a final method to create the results report.
In your solution make provision if a user has entered in an invalid result amount. Any result
entered that is below zero (0) is an invalid entry.
