Store user Input in ArrayList and remove it again
<p>I'm starting to make an ATM machine and are bumped into a problem.
It must be possible to create and delete new accounts to the user, and
user should be able to get a total of all his various accounts.
I imagine this must be done with an ArrayList, and a scanner that allows the user to enter their accounts. But since I am fairly new to this game, I have trouble connecting with these requirements of an ArrayList.
I hope you understand my problem and have the opportunity to help. Thanks in advance!</p>
