Java Encapsulation

Encapsulation bundling data and method together into a single unit. Encapsulation restricts direct access to prevent accidental modification of data.

Key Components of Encapsulation:

1. Data Hiding: Encapsulation hide data from others classes by defining the fields and method private.

2. Getter and Setter: Getter and setter used for access and update the value of private variable.

Example:

class Person{
    private String person_name; // private fields

    // getter method getPerson_name to get or access the person_name
    public String getPerson_name() {
        return person_name;
    }

    // setter method setPerson_name to modify the person_name
    public void setPerson_name(String person_name) {
        this.person_name = person_name;
    }
}
