Concepts of Object-oriented Programming


Book Description

There are many books on object-oriented programming for the professional programmer or designer who wants an in-depth knowledge. This is the first book for people that simply want to know what it is all about. It opens with a description of the differences between the procedural and object-oriented programming approaches. Then presents the basic concepts of object-oriented programming.




The Fundamental Concepts of Object-Oriented Programming


Book Description

Where does structured programming end and object-oriented programming (OOP) begin? What are OOP's fundamental concepts and what is the reason behind them? This book will answer these questions and will also give you an insightful perspective into OOP, based on its fundamental concepts. It is likely that you will have many "a-ha moments" reading this book and, at the end, you may even reach a feeling of "enlightenment".




Object-Oriented Programming Languages: Interpretation


Book Description

This comprehensive examination of the main approaches to object-oriented language explains key features of the languages in use today. Class-based, prototypes and Actor languages are all examined and compared in terms of their semantic concepts. This book provides a unique overview of the main approaches to object-oriented languages. Exercises of varying length, some of which can be extended into mini-projects are included at the end of each chapter. This book can be used as part of courses on Comparative Programming Languages or Programming Language Semantics at Second or Third Year Undergraduate Level. Some understanding of programming language concepts is required.




Concepts of Object-Oriented Programming with Visual Basic


Book Description

As the title suggests, this book has two separate - though intertwined - goals: a description of the general concepts of object-orientation, and how to do object-oriented programming in Visual Basic. Readers are assumed to have no more than a familiarity with Visual Basic and some rudimentary knowledge of programming. Working on this premise, Steve Roman introduces the abstract concepts of object orientation, such as class, abstraction, and encapsulation, and then shows how each is implemented in a meaningful and useful application. He uses a hands-on style throughout: plenty of code is given and discussed, including error-handling. As a result, Visual Basic programmers and students will find this an invaluable introduction to the topic.




The Object-oriented Thought Process


Book Description

The Object-Oriented Thought Process Third Edition Matt Weisfeld An introduction to object-oriented concepts for developers looking to master modern application practices. Object-oriented programming (OOP) is the foundation of modern programming languages, including C++, Java, C#, and Visual Basic .NET. By designing with objects rather than treating the code and data as separate entities, OOP allows objects to fully utilize other objects' services as well as inherit their functionality. OOP promotes code portability and reuse, but requires a shift in thinking to be fully understood. Before jumping into the world of object-oriented programming languages, you must first master The Object-Oriented Thought Process. Written by a developer for developers who want to make the leap to object-oriented technologies as well as managers who simply want to understand what they are managing, The Object-Oriented Thought Process provides a solution-oriented approach to object-oriented programming. Readers will learn to understand object-oriented design with inheritance or composition, object aggregation and association, and the difference between interfaces and implementations. Readers will also become more efficient and better thinkers in terms of object-oriented development. This revised edition focuses on interoperability across various technologies, primarily using XML as the communication mechanism. A more detailed focus is placed on how business objects operate over networks, including client/server architectures and web services. "Programmers who aim to create high quality software-as all programmers should-must learn the varied subtleties of the familiar yet not so familiar beasts called objects and classes. Doing so entails careful study of books such as Matt Weisfeld's The Object-Oriented Thought Process." -Bill McCarty, author of Java Distributed Objects, and Object-Oriented Design in Java Matt Weisfeld is an associate professor in business and technology at Cuyahoga Community College in Cleveland, Ohio. He has more than 20 years of experience as a professional software developer, project manager, and corporate trainer using C++, Smalltalk, .NET, and Java. He holds a BS in systems analysis, an MS in computer science, and an MBA in project management. Weisfeld has published many articles in major computer trade magazines and professional journals.




Python Object-Oriented Programming


Book Description

A comprehensive guide to exploring modern Python through data structures, design patterns, and effective object-oriented techniques Key Features Build an intuitive understanding of object-oriented design, from introductory to mature programs Learn the ins and outs of Python syntax, libraries, and best practices Examine a machine-learning case study at the end of each chapter Book Description Object-oriented programming (OOP) is a popular design paradigm in which data and behaviors are encapsulated in such a way that they can be manipulated together. Python Object-Oriented Programming, Fourth Edition dives deep into the various aspects of OOP, Python as an OOP language, common and advanced design patterns, and hands-on data manipulation and testing of more complex OOP systems. These concepts are consolidated by open-ended exercises, as well as a real-world case study at the end of every chapter, newly written for this edition. All example code is now compatible with Python 3.9+ syntax and has been updated with type hints for ease of learning. Steven and Dusty provide a comprehensive, illustrative tour of important OOP concepts, such as inheritance, composition, and polymorphism, and explain how they work together with Python's classes and data structures to facilitate good design. In addition, the book also features an in-depth look at Python's exception handling and how functional programming intersects with OOP. Two very powerful automated testing systems, unittest and pytest, are introduced. The final chapter provides a detailed discussion of Python's concurrent programming ecosystem. By the end of the book, you will have a thorough understanding of how to think about and apply object-oriented principles using Python syntax and be able to confidently create robust and reliable programs. What you will learn Implement objects in Python by creating classes and defining methods Extend class functionality using inheritance Use exceptions to handle unusual situations cleanly Understand when to use object-oriented features, and more importantly, when not to use them Discover several widely used design patterns and how they are implemented in Python Uncover the simplicity of unit and integration testing and understand why they are so important Learn to statically type check your dynamic code Understand concurrency with asyncio and how it speeds up programs Who this book is for If you are new to object-oriented programming techniques, or if you have basic Python skills and wish to learn how and when to correctly apply OOP principles in Python, this is the book for you. Moreover, if you are an object-oriented programmer coming from other languages or seeking a leg up in the new world of Python, you will find this book a useful introduction to Python. Minimal previous experience with Python is necessary.




Object-oriented Programming Featuring Graphical Applications in Java


Book Description

The goal of this book is to explore the principle ideas of object-oriented programming using the Java programming language. It begins teaching the object-oriented power of Java by relying on textual commands instead of emphasizing the AWT or Swing libraries, providing the reader with a simple, generic introduction to the OO concepts using Java (without the language details getting in the way of the concept presentation). The author provides a thorough introduction to the three fundamental concepts of object-oriented programming: Encapsulation, Inheritance, and Polymorphism. The presentation of OO theory is augmented by interleaved examples that illustrate these concepts. Most of these program examples are 2-D graphics programs that provide an intuitive context for the issues that must be addressed when learning OOP. Additionally, since graphics programming is one of the strengths of the Java development environment, the examples produce interesting and unexpected images that engage and motivate the reader. It contains a concise introduction to using Design Patterns particularly the Template Method, Iterator, and Composite design patterns which relate to the graphics examples in the book and uses UML class diagrams to show the static structure of systems and sequence diagrams to show object interactions. This book is appropriate for readers who are new to object-oriented (but have experience with a non-object-oriented language) and for programmers who want to learn the graphical elements and capabilities of Java.




Concepts in Programming Languages
