06. Encapsulation

Java Concept

Introduction

This concept is very important among the most commonly used. The meaning of encapsulation is to make sure that ‘sensitive’ data is hidden from users. to achieve this you must :

• Declare class variables/attributes as private
• provide a public get and set method to access and update the value of a private variable.

How do we use the above method and parameter passing? etc. is what this article is talking about.

What is the set and get?

• private variables can be accessed only by people of the same class.
• However, it is possible to access them if we provide a public get and set method.
• The get method returns the variable value, and the set method sets the value.
• Syntax for both is that they start with either get or set followed by the name of the variable, with the first letter in upper case.

Code example :

Conclusion

“If we use encapsulation, we must create get method and set method. And Flexible the programmer can change one part of the code without affecting other parts. Due to the increased security of data.”

GOOD LUCK!!!!!!
