Encapsulation

What is Encapsulation?

• Encapsulation is mechanism where we encapsulate the data (variables) and code acting on the data (methods) together as a single unit.
• In encapsulation, the variables of a class will be hidden from other classes, and can be accessed only through the methods of their current class. Therefore, it is also known as data hiding.
• To achieve encapsulation we need to declare the variables of a class as private and have to provide public setter and getter methods to modify and view the variables values.

Example:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20

public class EncapsulationDemo { private String id; private String name; public String getId() { return id; } public String getName() { return name; } public void setId(String newId) { id = newId; } public void setName(String newName) { name = newName; } }
