8/7/2023 0 Comments Objects first with java![]() ![]() As if learning java is not hard enough by itself. This sort of sloppiness makes it very hard to understand what is MEANT instead of SAID. But what is more important: This happens when an item with ANY index number is removed, except when it is the last item with the HIGHEST POSSIBLE index number. For starters, what is low and what is high is completely subjective. The problem for me is the wording 'with a low index number". One example: "If an item with a low index number is removed, then the collection moves all subsequent items along by one position to fill in the gap." When learning a programming language and al sorts of new concepts, I need language to be very precise. It makes me want to re-write almost every sentence. The style is very very sloppy and informal. Then I did an online java mooc at mooc.fi and now I am re-reading this book.Īnd I still think it is hard to understand. And this book has made a great use of that, with its clear writing style and slow yet deep exploration of the subject.Īt first I thought I did not understand this book because I did not understand java. Buy Objects First with Java: Practical Introduction Using BlueJ - With Access 6th edition (9780134477367) by David J. But I can say that it’s a great language to grasp the idea, concepts and techniques of object-oriented programming (OOP). Used again in chapter 8 to add inheritance. Is Java the best language to learn today? I can’t tell. A simple example with classes of students illustrates objects, fields, and methods. You’ll learn how to use subclasses, superclasses, abstract classes and methods, interfaces, subtyping, method dispatch and polymorphism, among other inheritance concepts. Approaching inheritance and choosing the right abstraction construct requires some thought and some practice, and these three chapters towards the end walk you through that in a gentle manner so you come out with a proper foundation. ![]() It’s the most substantial topic in the book and rightly so. Inheritance features heavily, with 3 entire chapters dedicated to it. This book won’t make you a competent Java programmer but it will still give you a deep understanding of the core concepts -often tricker parts- of the language, namely object-orientation and particularly inheritance. There are also various sections about functional programming. ![]() The only thing lacking is directed solutions for the activities, which, if I’m not mistaken, are only available for tutors. The book is generally designed to be supplemented with the presence of a tutor, but it is still entirely possible to make use of around 90% of the material if the subject is self-studied. This industry-leading text will take you from the first steps of learning objects to more sophisticated concepts and will help you explore and master the mechanics of running a program successfully.A deep dive into the world of object-oriented programming, using Java as the vehicle for this journey. The book's exploration of this new language demonstrates a renaissance of new functional ideas and techniques in modern programming, taking advantage of the boost in their popularity, in line with the new computing hardware available and the changing nature of current issues.Įxtensive use of the Java programming language and BlueJ – the Java interactive development environment.Ĭlear visualisation of BlueJ's classes and objects, allows you to gain a much better understanding of the differences than simply reading source code.Ĭhapters are ordered by software development concepts instead of language features, like in traditional textbooks.įunctional programming has become an essential part of the field. ![]() This latest edition goes beyond just adding the new language constructs of Java 8. Ideal for beginners but also more advanced students and professional programmers, the book begins with introductory chapters for students without any programming experience, with later chapters more suitable for advanced or professional programmers. Objects First with Java: A Practical Introduction, Global Edition, 6th Edition by Barnes and Kölling is an introduction to object-oriented programming, examining various programming concepts from a software engineering perspective. Tackle some of the biggest challenges in learning Functional Programming with this modern, up-to-date approach. ![]()
