Exploring Object Oriented Concepts

What is the primary goal of object-oriented design?

• To model real-world entities and their interactions using objects.

• To focus solely on data storage without behavior.

• To eliminate the need for programming altogether.

• To create a single, monolithic application.

Define encapsulation in the context of OOP.

• Encapsulation is the process of creating multiple instances of a class.

• Encapsulation is the method of exposing all data members of a class to the outside world.

• Encapsulation is the bundling of data and methods that operate on that data, restricting direct access to some of the object's components.

• Encapsulation refers to the inheritance of properties from a parent class.

What are the benefits of reusability in programming?

• Benefits of reusability include faster development, easier maintenance, reduced redundancy, improved consistency, and enhanced reliability.

• Limited code sharing opportunities

• Higher costs for development

• Increased code complexity

Explain the difference between procedural programming and OOP.

• OOP is based on functions, while procedural programming is based on classes.

• Procedural programming focuses on data structures, while OOP focuses on algorithms.

• Procedural programming is function-based, while OOP is object-based, focusing on data encapsulation and reusability.

• Procedural programming is only used for web development, while OOP is used for desktop applications.

What is inheritance and how is it implemented in OOP?

• Inheritance allows a child class to inherit attributes and methods from a parent class, promoting code reuse and establishing a class hierarchy.

• Inheritance is used to delete attributes from a parent class.

• Inheritance is a method to create multiple parent classes for a single child class.

• Inheritance allows a child class to override methods without any restrictions.

Describe the concept of abstraction in object-oriented programming.

• Abstraction involves implementing all details of an object without hiding any information.

• Abstraction is the process of creating multiple instances of an object.

• Abstraction is the technique of combining multiple classes into one.

• Abstraction is the process of hiding complex implementation details and exposing only the necessary features of an object.

What is the purpose of documenting design considerations?

• To create a checklist for design approval.

• To limit the scope of design discussions.

• To ensure comprehensive understanding and communication of design choices.

• To avoid any documentation of design changes.

How does Jackson Structured Development (JSD) differ from traditional structured design?

• Traditional structured design emphasizes iterative development more than JSD.

• JSD focuses solely on process design without considering data.

• JSD uses a linear approach to design, unlike traditional methods.

• JSD integrates data and process design more closely than traditional structured design.

What are associations in the context of object-oriented analysis?

• Associations are methods that define the behavior of a class.

• Associations are the processes that a class undergoes during execution.

• Associations are relationships between classes that define how instances of those classes interact with each other.

• Associations are attributes that store data within a class.

How can algorithms be optimized during the design phase?

• Using outdated programming languages

• Ignoring user feedback during development

• Algorithms can be optimized by analyzing problem requirements, selecting efficient data structures, applying suitable algorithmic techniques, and evaluating performance metrics.

• Focusing solely on aesthetics rather than functionality
