Encapsulation Example

A simple Java demonstration of encapsulation using a SavingsAccount class with private fields and public getter/setter methods.

Overview

This project illustrates the object-oriented programming principle of encapsulation in Java. A SavingsAccount class encapsulates account data (holder name, account number, and balance) behind private instance variables, exposing controlled access through public getter and setter methods. A Main class demonstrates creating an account object, reading its properties, and modifying them through the public interface.

Features

• Private instance variables enforcing data hiding
• Public getter and setter methods for controlled access
• Default and parameterised constructors
• Simple Main class demonstrating object creation and method usage

Prerequisites

• Java JDK 8 or higher
