It has nothing to do with how real banking work, so don’t worry if something do not make sense to you. A bank allow citizens to open accounts, each account must have an id, opening balance, account holder name, and age.

Definitely, you may have to Google the stuff that is related but not exactly same what we did in class. Before doing this task, I strongly recommend you to first run and understand the code samples we discussed in class that I have shared with you via Dropbox. It would help you to understand the basics and then you can build on those concepts to complete below given work. To better focus on different parts of the task, I have divided it in 4 sub-tasks, each sub-task UI is given in below mockup. 10.1 Create an option list with "multiple" property enabled, that means, user shall be able to select multiple options by holding the CTRL key.
