"Understanding object-oriented programming is vital for a modern computer programmer, and the Java programming language has been one of the most powerful tools available to computer programmers since its inception in 1995. It has also consistently changed since then, making it a vast and powerful resource for object-oriented programming today, finding many applications like mobile programming, Internet programming and software development. This lucid textbook introduces the student not only to the nuances of object-oriented programming, but also to the many syntaxes and semantics of the modern Java language. Each concept of programming is explained, and then illustrated with small but effective ready-to-run programs. Important points to be noted have been emphasized and hints have been given at the end of each discussion so that programmers are careful to avoid common pitfalls. Finally, a number of practice problems taken from real world scenarios encourage the student to think in terms of problem solving, consolidating the knowledge gained"--

As a programming language, Java's object-oriented nature is key to creating powerful, reusable code and applications that are easy to maintain and extend. That being said, many people learn Java syntax without truly understanding its object-oriented roots, setting them up to fail to harness all of the power of Java. This book is your key to learning both! This new third edition of Beginning Java Objects: From Concepts to Code discusses Java syntax, object principles, and how to properly structure the requirements of an application around an object architecture. It is unique in that it uses a single case study of a Student Registration System throughout the book, carrying the reader from object concepts, to object modeling, to building actual code for a full-blown application. A new chapter covers a technology-neutral discussion of the principles of building a three-tier architecture using Java, introducing the notion of model layer – presentation layer – data layer separation. Coding examples used throughout the book are Java version-neutral. The core object-oriented principles that you will learn from this book are timeless, and are relevant to all versions of the Java language, as well as to many other object-oriented languages. The book can be used for individual self-study or as a university-level textbook. What You Will Learn Know basic object-oriented principles, from the simplest notion of classes and objects through the power of encapsulation, abstract classes, and polymorphism Approach the requirements for an application to structure it properly around objects Render the resultant object model into Java code, building a complete functioning model layer for the Student Registration System case study Conceptually round out an object layer by adding presentation and data layers .

Applications built on the Salesforce platform are now a key part of many organizations' IT systems, with more complex and integrated solutions being delivered every day. As a Salesforce developer working with Apex, it is important to understand the range and variety of tools at your disposal, how and when to use them, and what the best practices are. This revised second edition includes a complete restructuring and five new chapters filled with detailed content on the latest Salesforce innovations including integrating with DataWeave in Apex, and utilizing Flow and Apex together to build scalable applications with Administrators. This Salesforce book starts with a discussion around common mistakes, debugging, exception handling, and testing. The second section focuses on the different asynchronous Apex programming options to help you build more scalable applications, before the third section focuses on integrations, including working with platform events and developing custom Apex REST web services. Finally, the book finishes with a section dedicated to profiling and improving the performance of your Apex including architecture. With code examples used to facilitate discussion throughout, by the end of the book you will be able to develop robust and scalable applications in Apex with confidence.

Welcome to the 2023 edition of International Workshop on Implementation, Compilation, Optimization of Object-Oriented Languages, Programs and Systems (ICOOOLPS 2023), held on July 17th at the University of Washington, Seattle, WA, co-located with ECOOP and ISSTA 2023. ICOOOLPS brings together researchers and practitioners working in the field of programming language implementation and optimization. Although its origins are attached to object-oriented approaches, it has since broadened its scope and now encompasses all programming language paradigms.

Leverage the power of Next.js to quickly produce efficient e-commerce sites. This project-oriented book will simplify the process of setting up a starter e-commerce site using Next.js from start to finish, creating a usable e-commerce offer with little more than a text editor or free software. It will equip you with a starting toolset you can use to develop future projects, incorporate into your existing workflow, and help you to take your websites to the next level, reducing reliance on tools that are bloated, prone to being hacked, and not the most efficient. Practical Next.js for E-Commerce is an excellent resource for getting started creating and manipulating e-commerce sites using a static site generator approach. It takes the view that you don’t have to create something complex and unwieldy; you can build something quickly, then extend it using the power of the API or plugins over time, without sacrificing speed or features. You will: Implement e-commerce sites using Next.js Explore some of the options for architecting an e-commerce site using this framework Work through a project from start to finish, understanding what can be achieved using Next.js, and where other tools may need to be brought into play.
