Q1. KOI Library need a new system to check PIN entry. You need to create an application to allow students to enter a PIN and validate it before they can access the library application.
You will need to use classes and Lists.
In the first question, create a program that will ask the librarian to enter student IDs and their PINs. It will use StudentPin class to create objects to save the ID and Pin (using a constructor). Each Student Pin object should then be added to a List which can hold objects of type StudentPin.
The program will keep asking if more Pins need to be entered(Y/N). For each ID and Pin entered, it will create the object and save it in a list. Once all IDs and Pins have been entered it should display the list in a tabular format.
Q2. Continuing with the same program as in Q1. Add code to ask the Students to enter their ID and Pin. First Check if the ID exists. Secondly check if they Pin matches. Confirm if they entered valid or invalid information.
