    I assumed that you have your Accounts class that contain name, accountCode, pinCode, balance.
    You can use the sort method of Collections under java.util class. Collections (Java Platform SE 7 )
    But it would cause a compilation error, (if Comparable interface did not implement by your Accounts class)
    so to do that, you implement first the Comparable interface under java.lang in your Accounts class Comparable (Java Platform SE 7 ) then implement its abstract method compareTo then do the comparison of balance. (Make sure to make your Comparable class generic to Accounts class if you are using java 6 or 7 so don't need to cast it)

    you can also use Comparator interface when sorting. But I think Comparable would be better
