Lab 5d: Transferring Funds

File BankAccount5d.java contains a definition for a simple bank account class with methods to withdraw, deposit, get the balance and account number, and print a summary. Save it to your directory and study it to see how it works. Then write the following additional code:

  1. Add transfer() function - Add a static method to the BankAccount5d class with the signature:

public static void transfer(BankAccount5d acct1, BankAccount5d acct2, double amount)

that lets the user transfer money between two accounts. Your new method should take two BankAccount5d objects and an amount and transfer the amount from the first account to the second account.

For example: If acct1 and acct2 are BankAccount5dobjects, then the call:

BankAccount5d.transfer(acct1, acct2,957.80);

shouldREMOVE$957.80 from acct1and ADD that amount to acct2. NOTE: Be sure to clearly document which way the transfer goes!

  1. New TransferTest5dclass - Write a class TransferTest5d with a main method that creates two bank account objectseach starting with $1000and enters a loop that does the following:
  • Prompt user for type of transfer - Asks if the user would like to:
  • Transfer money from account1 to account2
  • Transfer from account2 to account1
  • Quit.
  • If a transfer is chosen:
  • Prompt user for amount - If a transfer is chosen, asks the amount of the transfer
  • Carry out transfer - Carry out the transfer operation.
  • Print new balance - Print the new balance for each account.
  • Repeat until Quit -Repeats until the user asks to quit.

EXTRA CREDIT: In the transfer() methods, prevent the transfer from occurring if the source account doesn’t have enough money to withdraw and notify the user.
