Encapsulation With Example And Program In JAVA Encapsulation is one of the four key concepts in OOPS (Object Oriented Programming) namely Inheritance, Encapsulation, Abstraction and Polymorphism. Following definition helps you to understand the concept of encapsulation: In Java, encapsulation helps us to keep related fields and methods together, which makes our code cleaner and easy to read. It helps to control the values of our data fields. For example, Here, we are making the age variable private and applying logic inside the setAge () method. Now, age cannot be negative. Java is a class-based object-oriented programming (OOP) language that is built around the concept of objects.

Encapsulation in Java is a mechanism of wrapping 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.
