Through your fantastic book I have gained a tremendous amount of Java knowledge. The best book ever written on Java."- Ravindra Pai, Oracle Corporation, SUNOS product line"Bruce, your book is wonderful! Your explanations are clear and direct. Hawley, automation technician, Eli Lilly & Co."This is one of the best books I've read about a programming language. Hopefully I will be able to attend your seminar in the not-too-distant future."- Randall R. It's really cool to be able to understand the underlying principles and concepts from the start, rather than having to try to build that conceptual model through trial and error. I was really floundering (being a non-C programmer), but your book has brought me up to speed as fast as I could read it. IMHO, an ideal book for studying Java."- Anatoly Vorobey, Technion University, Haifa, Israel"Absolutely one of the best programming tutorials I've seen for any language."- Joakim Ziegler, FIX sysop"Thank you again for your awesome book. In contrast to many other Java books I found it to be unusually mature, consistent, intellectually honest, well-written, and precise. Very complete, with excellent right-to-the-point examples and intelligent, not dumbed-down, explanations. The exercises are challenging, and the chapter on Collections is superb! Not only did this book help me to pass the Sun Certified Java Programmer exam it's also the first book I turn to whenever I have a Java question."- Jim Pleger, Loudoun County (Virginia) Government"Much better than any other Java book I've seen. "Thinking in Java should be read cover to cover by every Java programmer, then kept close at hand for frequent reference. New coverage includesFunctional interfaces, lambda expressions, method references, and streamsDefault and static methods in interfacesType inference, including the diamond operator for generic typesThe annotationThe try-with-resources statementNew library features such as the Optional interface, java.time, and the convenience factory methods for collections Many new items have been added, including a chapter devoted to lambdas and streams. The third edition covers language and library features added in Java 7, 8, and 9, including the functional programming constructs that were added to its object-oriented roots. ![]() The comprehensive descriptions and explanations for each item illuminate what to do, what not to do, and why. As in previous editions, each chapter of Effective Java, Third Edition, consists of several "items," each presented in the form of a short, stand-alone essay that provides specific advice, insight into Java platform subtleties, and updated code examples. The support in modern Java for multiple paradigms increases the need for specific best-practices advice, and this book delivers. This Jolt award-winning classic has now been thoroughly updated to take full advantage of the latest language and library features. Packages are a feature of the Java programming language that help you to organize and structure your classes and their relationships to one another.Java has changed dramatically since the previous edition of Effective Java was published shortly after the release of Java 6. ![]() They improve the type safety of your code, making more of your bugs detectable at compile time. Generics are a powerful feature of the Java programming language. Numbers and Strings This lesson describes how to use Number and String objects The lesson also shows you how to format data for output. You will learn that all classes are derived from the Object class, and how to modify the methods that a subclass inherits from superclasses. That is, how a subclass can inherit fields and methods from a superclass. ![]() This section also describes the way in which you can derive one class from another. Interfaces and Inheritance describes interfaceswhat they are, why you would want to write one, and how to write one. This lesson describes where and how to use annotations in a program effectively. Language Basics describes the traditional features of the language, including variables, arrays, data types, operators, and control flow.Ĭlasses and Objects describes how to write the classes from which objects are created, and how to create and use the objects.Īnnotations are a form of metadata and provide information for the compiler. Feel free to skip this lesson if you are already familiar with object-oriented programming. This lesson ends by showing you how these concepts translate into code. Object-Oriented Programming Concepts teaches you the core concepts behind object-oriented programming: objects, messages, classes, and inheritance. This trail covers the fundamentals of programming in the Java programming language.
