Put condition in that loop if counter reaches max index of second array then make it 0 again to start from 0th index's element of array two.

that's why I've been asking around about ehcache

I'm only allowed to implement any kind of workaround so long I put it in my box and not changing anything in other boxes. oh well, if it's easy, anybody can do it right? that's why there's always obstacle, be it technical or "non-technical"

The process is up and running
Tomorrow a new type of customer is added by the business. Now how should I have written the process so that I can implement the new change without bringing down the existing process?
But this look to be error prone as it’s depending on the runtime input. And also can the new class added to the application can be implemented without stopping the running process. I tried but could not do it.
My take on this is that you have a process that is up and running 24/7 and you want to make changes without bringing it down. This usually involves having two or more copies of your program with a simple load balancer as a front end. Then you can temporarily suspend one of the running programs and bring it back on-line as a new version of the program. In the mean time the other running copies are handling the load. Repeat until all running copies have been updated.

You can have configuration files which you add customer types too. Or you can have databases which you add customer types to. But you will have to write some code somewhere whichever approach you take.

So, as the title says I'm trying to count the number of elements in an ArrayList which also have duplicates. So for example, in an ArrayList of strings which contains cat, cat, dog, horse, zebra, zebra, the answer should be two.
