By providing only a setter or getter method, you can make the class read-only or write-only. In other words, you can skip the getter or setter methods. It provides you the control over the data. Suppose you want to set the value of id which should be greater than 100 only, you can write the logic inside the setter method. You can write the logic no...

May 29, 2024 · Learn how to hide the implementation details of data and methods using encapsulation, a fundamental concept of object-oriented programming. See a Java program that demonstrates how to use private variables and public methods to achieve data hiding.
Encapsulation is one of the four fundamental Object-Oriented Programming (OOP) concepts, along with inheritance, polymorphism, and abstraction. It is a crucial concept in Java, and it involves bundling an object's state (fields) and behavior (methods) into a single unit known as a class.
