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
