Java OOPS Concept: Data Hiding( Access modifiers)

What is Data Hiding?

Data hiding restricts direct access to an object's internal fields, protecting them from unintended modification and exposing controlled access through methods.

Access Modifiers

• private: accessible only within the same class.
• default (no modifier): accessible within the same package.
• protected: accessible within the same package and by subclasses.
• public: accessible from anywhere.

Example

public class Account {
    private double balance;
    public double getBalance() { return balance; }
}
