programming paradigm

Question 2

two main paradigm

Answer 2

• Procedural programming
• Object Oriented Programming

Question 3

OOP

Answer 3

Object Oriented Programming

Question 4

a programming paradigm based on the concept of “objects”

Answer 4

Object Orented Programming

Question 5

OBJECTS can contain:

Answer 5

• data(attributes/ properties)
• methods(functions or behaviors)

Question 6

real life analogy, identify which is the attributes and methods
1. color, brand, speed
2. drive(), stop(), honk()

Answer 6

1. attributes
2. methods

Question 7

4 pillars of OOP

Answer 7

• encapsulation
• abstraction
• inheritance
  -polymorphism

Question 8

bundling data and methods into a single unit(class)

Answer 8

encapsulation

Question 9

t/f: encapsulation protects data from unauthorized access

Answer 9

true

Question 10

private fields with public getters/setter

Answer 10

encapsulation

Question 11

hiding complex implementation, showing only essential features

Answer 11

abstraction

Question 12

you use a tv remote without knowing how it works

Answer 12

abstraction

Question 13

• one interface, many forms
• a method behaves differently depending on the object

Answer 13

inheritance

Question 14

draw() method behaves differently in circle, square

Answer 14

inheritance

Question 15

Allows different classes to be treated as instances of the same class through method overriding.

Answer 15

polymorphism

Question 16

why used OOP

Answer 16

• code reusability
• easier to debug and maintain
• better organization
• closer to real-world modeling

Question 17

a paradigm used to develop complex software systems by organizing problems into objects

Answer 17

object-oriented programming

Question 18

combining data(attributes) and methods(functions) into one unit(class)

Answer 18

encapsulation

Question 19

promotes code reuse and logical hierarchy

Answer 19

inheritance

Question 20

t/f: encapsulation is a protective layer that ensures data integrity and restricts unauthorized access

Answer 20

true

Question 21

type of paradigms: Encapsulation can be performed through modularization, which groups data and functions into
procedures or functions. Information hiding can be implemented by careful function design.

Answer 21

procedural programming

Question 22

types of paradigm: prioritizes immutability, but
developers can still employ encapsulation
by constructing higher-order functions that
bundle data and behavior

Answer 22

Functional
programming

Question 23

how encapsulation works

Answer 23

• declare data members as private
• provide public methods (getter and setters)
• implements data validation

Question 24

benefits of encapsulation

Answer 24

• data protection
• security
• code reusabality
• maintainability

Question 25

a core principles of encapsulation, it involves limiting access to an objects internal state to preserve

Answer 25

data hidng

Question 26

by controlling access to data, ensuring consistency and valid

Answer 26

data integrityi

Question 27

isolating data within a class makes the code easier to understand, modify, and test

Answer 27

maintainability

Question 28

protecting sensitive data

Answer 28

security

Question 29

access modifiers in java

Answer 29

- default - protected - public - private

Question 30

accessible within the same package

Answer 30

default

Question 31

accessible only within the class

Answer 31

private

Question 32

accessible from any other class

Answer 32

public

Question 33

accessible within the same package and subclasess

Answer 33

protected

Question 34

only accessible within its own class. classes and interfaces can not be declared private

Answer 34

private

Question 35

getter/setters : returns the value of private variable

Answer 35

getter

Question 36

getter/setters : updates the value with validation if needed

Answer 36

setters

Question 37

t/f: getters and setters enhance code security and maintain proper data handling

Answer 37

true

Question 38

blueprint/ template

Answer 38

classes
