Counting Transactions

Suppose the bank wanted to keep track of the total number of deposits and withdrawals (separately) for each day, and the total amount deposited and withdrawn. Write code to do this as follows:

1. Add four private static variables to the Account class, one to keep track of each value above (number and total amount of deposits, number and total of withdrawals). Note that since these variables are static, all of the Account objects share them. This is in contrast to the instance variables that hold the balance, name, and account number; each Account has its own copy of these. Numeric static and instance variables are initialized to 0 by default.
   
2. Add public methods to return the values of each of the variables you just added, e.g., public static int getNumDeposits().
   
3. Modify the withdraw and deposit methods to update the appropriate static variables at each withdrawal and deposit.
   
4. File ProcessTransactions.java contains a program that creates and initializes two Account objects and enters a loop that allows the user to enter transactions for either account until asking to quit. Modify this program as follows:
   • After the loop, print the total number of deposits and withdrawals and the total amount of each. You will need to use the Account methods that you wrote above. Test your program.
   • Imagine that this loop contains the transactions for a single day. Embed it in a loop that allows the transactions to be recorded and counted for many days. At the beginning of each day print the summary for each account, then have the user enter the transactions for the day. When all of the transactions have been entered, print the total numbers and amounts (as above), then reset these values to 0 and repeat for the next day. Note that you will need to add methods to reset the variables holding the numbers and amounts of withdrawals and deposits to the Account class. Think: should these be static or instance methods?
