Due to various language constraints, lambda expressions had, until recently, never made it into the Java language. The concept had long been baked into other languages, such as Groovy andRuby. That all changed
new Thread( () -> System.out.println("In Java8, Lambda expression rocks !!") ).start(); } } 输出: Before Java8, too much code for too little to do In Java8, Lambda expression rocks !! 这个例子向我们展示了Java 8 lambda表达式的语法。你可以使用lambda写出如下代码: (params) -> expre...

The biggest new feature of Java 8 is language level support forlambda expressions(Project Lambda). A lambda expression is like syntactic sugar for an anonymous class1with one method whose type is inferred. However, it will have enormous implications for simplifying development. 2.1Syntax The main ...
JDK 8 Release Notes Java Programming Language Lambda Expressions, a new language feature, has been introduced in this release. They enable you to treat functionality as a method argument, or code as data. Lambda expressions let you express instances of single-method interfaces (referred to as fun...
