Java 8was released in early 2014. This tutorial list down importantJava 8 featureswith examples such as lambda expressions, Java streams, functional interfaces, default methods and date-time API changes. 1. Lambda Expressions Lambda expressionsare known to many of us who have worked on other popu...

Java SE 8’s stream API 是为了帮助管理数据集合而设计的,这些对象是指集合框架中的对象,例如数组列表或哈希表。但是,你也可以直接从数组创建流。 如何工作? 在Java8Features 项目中的 eg.com.tm.java8.features.stream.creating 包下,我创建了一个名为ArrayToStream的类。在这个类的 main 方法中,我创建了一...
Lambda表达式是Java 8最具有争议和最引人注目的新特性之一。Lambda表达式提供了一种简洁的语法，可以将函数作为参数传递给其他函数，这极大地提高了代码的可读性和可维护性。Lambda表达式的语法非常简单，可以用一行代码表示，例如：list.forEach((String s) -> System.out.println(s));这个例子演示了Lambda表达式的...
