دستورهای جاوا ۸، ویرایش دوم

__Java 8 Recipes__ offers solutions to common programming problems encountered while developing Java-based applications. Fully updated with the newest features and techniques available, __Java 8 Recipes__ provides code examples involving Lambdas, embedded scripting with Nashorn, the new date-time API, stream support, functional interfaces, and much more. Especial emphasis is given to features such as lambdas that are newly introduced in Java 8. Content is presented in the popular problem-solution format: Look up the programming problem that you want to solve. Read the solution. Apply the solution directly in your own code. Problem solved! The problem-solution approach sets __Java 8 Recipes__ apart. __Java 8 Recipes__ is focused less on the language itself and more on what you can do with it that is useful. The book respects your time by always focusing on a task that you might want to perform using the language. Solutions come first. Explanations come later. You are free to crib from the book and apply the code examples directly to your own projects. * Covers the newly-released Java 8, including a brand new chapter on lambdas * Focuses especially on up-and-coming technologies such as Project Nashorn and Java FX 2.0 * Respects your time by focusing on practical solutions you can implement in your own code 2-8.
