Core Java Simply In Depth

This text is an introduction to the complex world of the Java Technologies. This book encapsulates rich practical hands-on experience in developing web applications, combined with teaching the subject for graduate/post-graduate students. The book is therefore a culmination of putting together what has been both practiced as well as preached, which is the one of the most compelling differentiators for this book. But what is more fascinating is the nature of the web itself. It can also be used for independent study by anyone interested in getting a broad introduction to a core useful subset of the many technologies of Java. This 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. Many new items have been added, including a chapter devoted to lambdas and streams.New coverage includes: ●Functional interfaces, lambda expressions, method references, and streams. ● Default and static methods in interfaces. ● Type inference, including the diamond operator for generic types. ● The @SafeVarargs annotation. ● The try-with-resources statement.● New library features such as the Optional interface, java.time, and the convenience factory methods for collections.
