Checkbook-OldStyle

Create a simple Checkbook class that adheres to java Collections interface.

A new company, ZipMintyFreshness, needs a checkbook account object inside their new mobile offering.

You need to create a class, and 3 tests for every method.

Maybe you'll get paid.

Checkbook needs to organize and track a series of Transaction objects. See the Transaction class file. Transaction needs to use a few Payee objects for your tests.

• int size()
• boolean isEmpty()
• boolean contains(Transaction element)
• boolean add(Transaction element)
• boolean remove(Transaction element)
• Iterator iterator()

AND

• Transaction[] toArray()

• Transaction[] toArray(Transaction[] a)

• double checkbookValue() // sum of all Transactions (both Debits and Credits)

• Transaction getTransactionsForDate(LocalDate aDate)

• Transaction[] getAllTransactionsForPayee(Payee payee)

• Transaction[] getAllDebitTransactions()

• Transaction[] getAllCreditTransactions()

Special Constructors:

• Checkbook(double cashAmount)
• Checkbook(Payee owner, double cashAmount)

PLUS (For Extra Points, 10 million extra, to be precise)

• containsAll(Collection c)
• boolean addAll(Collection c)
• boolean removeAll(Collection c)
• void clear()

finally, make a generic account class, that takes any class which implements the AccountBook interface.
