Encapsulation chapter of Class 10 Computer Applications delves into the concept of Encapsulation, a fundamental aspect of object-oriented programming. Encapsulation involves bundling data (attributes) and the methods (functions) that manipulate the data into a single unit, known as a class. This encapsulation ensures that the internal workings of an object are hidden from the outside world, allowing controlled access to data, promoting security, and facilitating efficient code management. Solving ICSE class 10 computer important questions will help students understand the concepts better.

What are Encapsulation?

Encapsulation is a fundamental principle in object-oriented programming (OOP) where the data (variables) and the methods (functions) that operate on the data are bound together within a single unit known as a class. Solving  Encapsulation important questions for class 10 ICSE  essential for a comprehensive understanding and successful examination preparation. Explore further with oswal.io  for ICSE class 10 important questions 2023-24  to strengthen your knowledge in these fundamental areas of computer.

Class 10 Encapsulation Important Questions and Answers

Q1. What is the proper access specifier for data members of a class?


(a) Private
(b) Default
(c) Protected
(d) Public

Ans. (a) Private

All the data members should be made private to ensure the highest security of data. In special cases we can use public or protected access, but it is advised to keep the data members private always.

Q2. ___________ keword is used while creating a static method.


(a) Static
(b) Final
(c) Instance
(d) Nostat

Ans. (b) Final
A static method definition must start with the static keyword.

Q3. What is meant by private visibility of a method ?

Private methods can be used in the class in which they are defined. Outside that class they cannot be accessed.

Q4. Differentiate between private and protected visibility modifiers.

Private is the most restricted access specifier which is accessible only in its own class.Protected members are accessible by the classes of the same package or by a child class in any other package.

Q5. In the program given below, state the name and the value of the:
(i) method argument or argument variable.
(ii) class variable.
(iii) local variable.
(iv) instance variable
      class myClass.
            static int x = 7;
            int y = 2;
            public static void main(String args[])
                  myClass obj = new myClass();
                  int a = 6;
                  void sampleMethod(int n)

(i) int n; (argument variable)
(ii) x = 7; (class variable)
(iii) a = 6; (local variable)
(iv) y = 2; (instance variable)

Frequently Asked Questions

Q1 : What is Encapsulation in Object-Oriented Programming?

Ans:  Encapsulation is the mechanism of bundling data (attributes) and methods (functions) that manipulate the data into a single unit (class).

Q2 : How does Encapsulation Achieve Data Security?

Ans:  Encapsulation restricts access to certain components within a class, enabling data hiding and protecting it from unwanted access or modification.

Q3 : Why is Encapsulation Important in Software Development?

Ans: Encapsulation promotes code organization, modularity, and better maintainability by hiding the internal workings of an object and exposing only necessary functionalities.

Q4 : How Does Encapsulation Differ from Abstraction?

Ans: Encapsulation focuses on bundling data and methods together, while abstraction emphasizes showing only the essential features of an object and hiding its complexity.

Q5 : Can Encapsulation Enhance Security in Software Systems?

Ans: Yes, encapsulation can improve security by preventing unauthorized access to sensitive data and ensuring that data can only be manipulated through controlled methods.
