Beskrivelse
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 LearnKnow basic object-oriented principles, from the simplest notion of classes and objects through the power of encapsulation, abstract classes, and polymorphismApproach the requirements for an application to structure it properly around objectsRender the resultant object model into Java code, building a complete functioning model layer for the Student Registration System case studyConceptually round out an object layer by adding presentation and data layers Who This Book Is ForSoftware developers who have never tackled Java as a programming language, as well as those who have already used Java but want to ensure that they are taking full advantage of the object-oriented nature of the language
