Final answer:
A company has written a large class BankingAccount with many methods, including:withdrawCash()
The answer is option ⇒A
Step-by-step explanation:
The withdrawCash() method in the BankingAccount class allows account holders to withdraw money from their account. This method is an essential part of any banking system as it enables customers to access their funds.
Here's how the withdrawCash() method typically works:
- 1. Parameters: The withdrawCash() method may require one or more parameters, such as the amount of money to be withdrawn and the account from which the withdrawal should be made.
- 2. Validation: Before processing the withdrawal, the method may perform validation checks. For example, it may verify that the requested amount is within the available balance or that the account is not frozen or closed.
- 3. Deducting the amount: Once the validation is successful, the withdrawCash() method deducts the requested amount from the account balance. This ensures that the account reflects the updated balance after the withdrawal.
- 4. Recording the transaction: The method may also record the withdrawal as a transaction in the account history. This can be useful for future reference and tracking.
- 5. Returning the result: After completing the withdrawal process, the method typically returns a confirmation message or status to indicate whether the withdrawal was successful or not. This can be helpful for both the account holder and the system administrators to track the transaction status.
Here's an example of how the withdrawCash() method could be implemented in Java:
```java
public class BankingAccount {
// Other class members and properties
public void withdrawCash(double amount, Account account) {
if (account.isFrozen()) {
System.out.println("Sorry, your account is frozen. Please contact customer support.");
return;
}
if (amount <= 0) {
System.out.println("Invalid withdrawal amount. Please enter a positive value.");
return;
}
if (amount > account.getBalance()) {
System.out.println("Insufficient balance. Please enter a lower amount.");
return;
}
// Deduct the amount from the account balance
account.setBalance(account.getBalance() - amount);
// Record the transaction
account.addTransaction(new Transaction(TransactionType.WITHDRAWAL, amount));
System.out.println("Withdrawal of $" + amount + " successful. Current balance: $" + account.getBalance());
}
}
```
In this example, the withdrawCash() method checks if the account is frozen, validates the withdrawal amount, deducts the amount from the account balance, records the transaction, and returns an appropriate message to the user.
The answer is option ⇒A
