 # Checkbook-OldStyle
 
-create a simple checkbook class that adheres to java Collections interface.
+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<Transaction> iterator()
+ 
+ AND
+ 
+ * Transaction[] toArray()
+ * <Transaction> Transaction[] toArray(Transaction[] a)
+ 
+ * double checkbookValue() // sum of all Transactions (both Debits and Credits)
+ * Transaction getTransactionsForDate(LocalDate aDate)
+ * Transaction[] getAllTransactionsForPayee(Payee payee)
+ 
+ Special Constructors:
+ * Checkbook(double cashAmount)
+ * Checkbook(Payee owner, double cashAmount)
+ 
+ 
+ PLUS (For Extra Points, 10 million extra, to be precise)
+ 
+ * containsAll(Collection<Transaction> c) 
+ * boolean addAll(Collection<Transaction> c)
+ * boolean removeAll(Collection<Transaction> c)
+ * void clear()
