What does encapsulation mean: In object-oriented computer programming (OOP) languages, the notion of encapsulation (or OOP Encapsulation) refers to the bundling of data, along with the methods that operate on that data, into a single unit. Many programming languages use encapsulation frequently in the form of classes.
What is difference between polymorphism and encapsulation?
Polymorphism allows program code to have different meaning or functions while encapsulation is the process of keeping classes private so they cannot be modified by external codes.
What is Java encapsulation?
Encapsulation is one of the key features of object-oriented programming. Encapsulation refers to the bundling of fields and methods inside a single class. It prevents outer classes from accessing and changing fields and methods of a class. This also helps to achieve data hiding.
What is difference between encapsulation and abstraction?

What is encapsulation and abstraction in OOPs?
Abstraction is a feature of OOPs that hides the unnecessary detail but shows the essential information. Encapsulation is also a feature of OOPs. It hides the code and data into a single entity or unit so that the data can be protected from the outside world. It solves an issue at the design level.
What is encapsulation in Java?
Encapsulation in Java is a powerful mechanism for storing the data members and data methods of a class together. It is done in the form of a secure field accessible by only the members of the same class.
Which of the following is an example of encapsulation?

What is encapsulation type?
Generally, Encapsulation is a process by which a lower-layer protocol receives data from a higher-layer protocol and then places the data into the data portion of its frame. Thus, encapsulation is the process of enclosing one type of packet using another type of packet.
