ArrayList problems

[Nandomo]

I am making an ATM machine and trying to get my accounts from a .csv file to an ArrayList and am having all sorts of issues. Can I get help? It is giving me problems on line 52 of the class where I read and put the items into Arraylist.

Integer.getInteger(tempNum) returns an Integer object, but your bsnk account constructor requires an int value. Have a look at Integer.parseInt(...)
(Etc)
