Question

CappedChecking – represents a checking account that disallows a balance above a particular maximum value.

Class CappedChecking - deposit - deposits a given amount into the account as described previously link - given an account acct, link this account with acct

account will be labeled as Filterable.That is,you must appropriately define an abstract class or interface representing the filterable notion. Each such filterable class must implement the method boolean accept() which returns true or false based on the following criteria: The minimum amount for a checking account is $0. There is no maximum for a standard checking account, while capped checking accounts have maximum $10000.
