Introduction

Chapter 2, "Class as a Basis of all Computation," in Class 10 Computer Applications delves into the foundational aspects of classes and objects within programming. This segment introduces students to the fundamental principles of object-oriented programming (OOP), emphasizing the role of classes as the building blocks for creating objects in computer applications. Understanding this chapter lays the groundwork for comprehending advanced programming concepts and their practical applications in software development along with answering ICSE class 10 computer important questions of Class as a Basis of all Computation.

What are Class as a Basis of all Computation?

Class as a Basis of all Computation refers to the fundamental concept in object-oriented programming (OOP) where a "class" acts as a blueprint or template to create objects. Classes encapsulate data (attributes) and behaviors (methods) into a single unit, allowing the creation of multiple objects with similar attributes and functionalities. Practising important questions for class 10 ICSE of Class as a Basis of all Computation 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 Class as a Basis of all Computation Important Questions and Answers

Q1. A static method is also called a :

Options

(a) Instance function
(b) Defined function
(c) Class method
(d) Fixed function

Ans. (c) Class method

Explanation:
A static method, or a class method in Java, is a method associated with the class itself rather than with a particular instance of the class.

Q2. What is the precision of the double data type ?

Options

(a) 5 digits 
(b) 7 digits
(c) 15 digits 
(d) 10 digits

Ans. (c) 15 digits 
Explanation:
A float in Java can accurately hold up to 7 decimal digits, whereas a double can accurately hold up to 15 decimal digits.

Q3. What are member variables ? State their access modifiers.

Explanation:
Member variables are also known as instance variables. These member variables are used to store value in the class. It may be public, private, protected or with no access modifiers where private , protected and members with no access modifiers remain hidden from outside world and thereby support data-hiding.

Q4. Write the method to define a class.

Explanation:
A class is declared by using the keyword ‘class’. The general form of a class definition is shown below :
class < class name >
{
     data type - instance variable 1;
    data type - instance variable 2;
     type method name 1 (parameter list)
     {
         body of method
     }
}

Q5.  Define class ? Give example of class and object.

Explanation:
A class may be thought of as a ‘data type’, classes are user-defined data types and behave like the built in types of a programming language. If furniture has been defined as a class, then sofa will be its object. Sofa belongs to the class ‘Furniture’.

Frequently Asked Questions

Q1 : What is the significance of classes in programming?

Ans: Classes serve as templates or blueprints that define the structure and behavior of objects in programming. They encapsulate data (attributes) and functionalities (methods), promoting code reusability and organization.

Q2 : How do classes facilitate object creation in computer applications?

Ans:  Classes define the properties and behaviors that objects will possess. To create objects, one utilizes these class definitions as templates, instantiating multiple instances of objects based on the defined class structure.

Q3 : Can you explain the relationship between classes and objects in programming?

Ans: Classes act as templates or blueprints that define the structure and behavior of objects. Objects, on the other hand, are instances or realizations of these classes, possessing specific attributes and behaviors as defined in the class.

Q4 : What are the key components that comprise a class?

Ans: A class comprises attributes (variables) and methods (functions). Attributes represent the data or properties of an object, while methods define its behaviors or actions.

Q5 : How does encapsulation contribute to the effectiveness of classes in software development?

Ans: Encapsulation refers to bundling the data (attributes) and methods (functions) within a class. It ensures data security by controlling access to the internal components of an object, enhancing code maintainability and reusability.
