Question
In this part you will handle a new kind of transaction called a transfer where money is moved from one account to
another account. Implement the method:
• public boolean transferFromOneToAnother(String fromName, String toName, double amount) - Make a
transfer from one account (fromName) to another (toName). Return true if funds are sufficient for transfer
(otherwise false ). (Hint: this is similar to the two methods from Part 2, but you need to think a bit about the
success/failure cases.)
In the input file, transfers are indicated by listing two account handles and an amount, like lines 2, 4 and 6 of the file
input6.txt where funds are transferred from Alice to Bob and vice versa:
DEPOSIT Alice 300
Alice Bob 150
DEPOSIT Alice 400
Alice Bob 250
WITHDRAW Bob 200
Bob Alice 600
The result of running it should look like this:
% javac-introcs TigerCoin.java
% java-introcs TigerCoin < transactions/input6.txt
DEPOSIT -> Alice : 300.0 (success: true)
Alice -> Bob : 150.0 (success: true)
DEPOSIT -> Alice : 400.0 (success: true)
Alice -> Bob : 250.0 (success: true)
WITHDRAW -> Bob : 200.0 (success: true)
Bob -> Alice : 600.0 (success: false)
All account balances:
Alice: $300.00
Bob: $200.00
