clear logic
"Java Core Technology" is divided into two volumes, I and II. Volume I: mainly introduces the professional-level detailed explanation of the basic knowledge of the Java language; Volume II: mainly introduces the advanced topics that software development needs to know. A comprehensive introduction to Java program development. The comprehensiveness of this book is not a simple listing, but through careful organization, a clear main line is sorted out from the complicated content of Java to form a complete knowledge system.
In Volume 1 Basics, the first 2 chapters are like a "prelude", which will introduce the background and features of the Java language, and give a detailed installation guide to build a stage for learning Java development. In the next few chapters, the main actors in a Java program come into play: encapsulation, inheritance, interfaces, exception handling, generics, collections. These are the core of Java development, and with this knowledge, you can write practical programs to solve practical problems. The final chapter introduces parallelism, which is where applications are heading today. The entire book will not only give you an in-depth understanding of all the basics and Java features involved in designing and implementing Java applications, but also help you master all the basic skills needed to develop Java programs.
thorough
This book well avoids the "big and general" problem that is easy to make in the development of basic books. Although the content is extensive, the introduction of knowledge points is not general. Taking object construction as an example, based on an accurate understanding of the basic concepts of constructors, it deeply analyzes related issues such as overloading, default field initialization, parameterless constructors, initialization blocks, calling other constructors, and object destructuring, so that you can To deal with specific problems that you may encounter during the development process, not only know how to do it, but also know why you do it.
easy to use
Learning a language is not easy, especially a language as huge as Java. But this book will make your learning journey easier. The text in the book is easy to understand. It often uses metaphors to give us a concrete understanding of abstract concepts. A lot of comments, tips and warnings are given. These are the summary of the author's actual experience, which will greatly benefit programming practice. benefit.
