Manning's bestselling Java 8 book has been revised for Java 9 and 10! In Modern Java in Action, you'll build on your existing Java language skills with the newest features and techniques. .. eBook $ pdf + ePub + site + liveBook. Java 8 in Action is a clearly written guide to the new features of Java 8. The book covers lambdas, streams, and functional-style programming. With Java 8's.

Using parallel streams correctly. Using parallel streams effectively. Working with RecursiveTask. Spliterator 7.

The splitting process. Implementing your own Spliterator. Refactoring, testing, and debugging 8. Refactoring for improved readability and flexibility 8. Improving code readability. From anonymous classes to lambda expressions. From lambda expressions to method references.

From imperative data processing to Streams. Refactoring object-oriented design patterns with lambdas 8. Testing lambdas 8. Testing the behavior of a visible lambda. Focusing on the behavior of the method using a lambda. Pulling complex lambdas into separate methods. Debugging 8. Examining the stack trace. Default methods 9. Evolving APIs 9. API version 1. Usage patterns for default methods 9.

Optional methods.

Multiple inheritance of behavior. Resolution rules 9. Three resolution rules to know.

Most specific default-providing interface wins. Conflicts and explicit disambiguation.

Using Optional as a better alternative to null How do you model the absence of a value? Reducing NullPointerExceptions with defensive checking. What are the alternatives to null in other languages? Introducing the Optional class. Patterns for adopting Optional Creating Optional objects. Extracting and transforming values from optionals with map. Chaining Optional objects with flatMap.

Default actions and unwrapping an optional.

What does "return the same object" mean? Introduction to Scala Modern Java in Action connects new features of the Java language with their practical applications. Using crystal-clear examples and careful attention to detail, this book respects your time.

My Java code improved significantly after reading this book. I was able to take the clear examples and immediately put them into practice. Modern Java in Action.

Part 1: Fundamentals 1 Java 8, 9, 10, and Remember behavior parameterization. Use a functional interface to pass behaviors. Execute a behavior! Pass code.

Use an anonymous class. Use lambda expressions. Use method references. Traders and Transactions. Pythagorean triples. Comparing Java and Scala Yet another modified a class to be a singleton. In addition, there was a metaclass to support the conversion of plain-old classes into replicated classes in the context of the SOM Replication Framework, which was programmed by Hari Madduri and Ira.

These experiences convinced Ira that reflective programming is cool. Allowing those innovations to be lost was unacceptable. So, while employed to work on other matters, Ira and Scott pushed on to write Putting Metaclasses to Work, which was published in The resulting paper led to some interesting insights into both reflection and patterns.

But most of all, it reinforced our conviction that reflective programming is cool. Nate graduated and went to work as a Java developer, first at Liaison Technology and currently at Ticom Geomatics. Nate was able to leverage Java reflection to the benefit of his employers, producing flexible application frameworks and APIs.

With this value in mind, we teamed up to teach reflection. This father and son team will be forever grateful for that suggestion.

We hope that, through this book, you will find Java reflection as cool and valuable as we do. The world, however, wanted something else, as was evident by the astoundingly rapid rise of Java to preeminence in object-oriented programming. Now, the battle for control of the architecture of object-oriented programming has moved to C versus Java. Control of an architecture is where the big money is made in information technology. Ferguson and Charles R. Morris Random House, We are grateful to Dewayne Perry for giving us the opportunity to teach this material in the Software Engineering Program at the University of Texas.

We also thank the students who persevered as we honed our explanations of reflection. Your detailed and helpful comments have made this a better book. Special thanks to Norman Richards who reviewed the final manuscript for technical acurracy shortly before it went to press. In particular, we thank Marjan Bace—the publisher who recognized the importance of reflection and whose eye for organization and style was tremendously helpful.

Jackie Carter—our development editor, whose insights improved the manuscript dramatically and whose advice guided us through the process. David Roberson—who arranged for manuscript reviews and provided comments. Linda Recktenwald—who performed a really great editing job. Dottie Marsico—who did the typesetting and the graphics. Susan Forsyth—who ensured quality and did not falter during the last phase of production.

Mary Piergies—who managed the production team and got the book out the door. Throughout this book, we follow a fictional character, George the programmer.

Sometimes these stories were from our own experience. Many other times, these stories were inspired by coworkers. Your experiences have taught us—thank you.First-class functions in Scala. A limited number of pBook copies of this edition are still available. Part VI of this book describes a series of web-enabled systems for order configuration built around the Jess rule engine using Java servlets and JavaServer pages. Generalized summarization with reduction.
