/*
Experiment No. 3: Bank Account Management
Aim
To study the use of Access Specifiers (Public, Private, Protected, and Default) in Java.
Problem Statement
Create a BankAccount class with the following data members:
• Account Number – public
• Balance – private
• Branch Name – protected
• Bank Code – default
Create appropriate methods to:
1. Initialize the account details.
2. Access the private member using public methods.
3. Display all account details.
4. Explain the accessibility of each access specifier.
