Hi all
In my Data.java i have the following code that opens the datafile accordingly and attempts to make use of a cache P.s If i violate any code pls feel free to edit my posts accordingly):


When i try to run it i get the following error:





D:\Developer>java -jar runme.jar alone
Exception in thread "main" java.lang.IndexOutOfBoundsException: Index: 0, Size:
0

I really dont know how to handle the problem. At first i figured it was that i didnt set an initial capacity for the arraylist, but right now after doing that it doesnt still change. Your insight into the problems will highly be appreciated

The set() method replaces the element at the specified position in this list with the specified element. You do not have any element in the array now.

Try to use add() method.
