In a banking application, private access modifiers are appropriate for securing sensitive data and methods. Consider a BankAccount class with attributes like accountNumber, balance, and methods like
deposit() and
withdraw(). To maintain security and prevent unauthorized access or manipulation of these attributes and methods, they should be declared as private.
Using private access modifiers ensures that only the BankAccount class’s methods can directly access and modify its attributes. This encapsulation prevents external classes from tampering with the data, ensuring consistency and integrity. Additionally, it allows developers to change the implementation details without affecting other parts of the codebase, promoting maintainability.
For example:
class BankAccount {
private int accountNumber;
private double balance;
private void deposit(double amount) { /*...*/ }
private void withdraw(double amount) { /*...*/ }
}?
In this scenario, using private access modifiers is crucial for protecting sensitive information and maintaining proper functionality within the banking application.
