Java 8 is a giant step forward for the Java language. Writing this book has forced me to learn a lot more about it. In Project Lambda, Java gets a new closure syntax, method-references, and default methods on interfaces. It manages to add many of the features of functional languages wit...
}).start();//Java 8方式:相当于自动重写了run方法newThread( () -> System.out.println("In Java8, Lambda expression rocks !!") ).start(); } } 输出: BeforeJava8,too much code for too little to do InJava8,Lambda expression rocks !! 这个例子向我们展示了Java 8 lambda表达式的语法。你可...

there is a chance for inconsistent data. In other words, one copy of the data might reflect the up-to-date value, but another copy might still have the previous value. In the Lambda Architecture, since the data is processed sequentially (and not in parallel with overlap, which may be the...

signature. In other words, this signature is a guarantee that if you passArray<Number>tofilter, the first parameter to the lambda will be type Number, and the output will beArray<Number>as well. If you’re familiar with generics from other languages like Java or Scala, this should l...
