课程名称：Java 8 新特性 课程概述：Oracle 的 Java 8 发布标志着全球最受欢迎的开发平台历史上的一个重要时刻。这一版本不仅在 Java 编程范式上进行了显著改进，还对 JVM、Java 语言和库进行了协调更新。这次更新包含了许多新特性，提升了易用性、生产力和安全性，同时改善了系统整体性能。 在 Java 8 中，引入了一种新的概念——函数式接口。函数式接口是指恰好有一个抽象方法的接口。我们并不需要使用 @FunctionalInterface 注解来指定一个接口为函数式接口，但使用该注解可以防止意外添加额外的抽象方法。与 @Override 注解类似，推荐使用它。java.lang.Runnable 是一个优秀的函数式接口的示例，因为它只有一个抽象方法 run()。函数式接口的一个引人注目的特性是可以通过 Lambda 表达式创建对象。 本课程详细介绍了 Java 8 的所有特性，提供了丰富的示例。完成课程后，您将对 Java 8 的特性有很扎实的知识理解。 教程包含以下主题： 1. Lambda 表达式 2. 函数式接口 3. 接口中的默认方法 4. 接口中的静态方法 5. Predicate 6. Function 7. Consumer 8. Supplier 9. 方法引用与构造函数引用（使用双冒号 (::) 操作符） 10. Stream API 11. CompletableFuture 12. 日期与时间 API 通过本课程的学习，您将全面掌握 Java 8 的新特性，提升您的编程技能。
Oracle's Java 8 release was a watershed moment in the history of the world's most popular development platform. In addition to a significant improvement to the Java programming paradigm as a whole, the JVM, Java language, and libraries were all updated in a coordinated manner. Many new features were included in this update, including enhanced simplicity of use, increased productivity and security, and overall better system performance.In Java 8, a new notion called functional interfaces was introduced. A Functional Interface is an interface that has exactly one abstract method. To designate an interface as a Functional Interface, we don't need to use the @FunctionalInterface annotation.The @FunctionalInterface annotation prevents abstract methods from being accidentally added to functional interfaces. It's similar to a @Override annotation, and it's recommended that you use it. java.lang. Runnable is a fantastic example of a functional interface since it has one abstract method, run ().One of the most appealing features of the functional interface is creating objects using lambda expressions.In this tutorial I have covered all features of Java8 in very details with lot of example. I am sure once you finish this course you will have very sound knowledge of java8 featuresThese are the topics are included in this tutorial.1. Lambda Expressions2. Functional Interfaces3.
