API in Java is delivered via Java Development Kit or JDK. JDK is made up of three entities. Java compiler: A pre-quoted program used for breaking the complex user-written codes into simple and computer-understandable codes, known as byte-code. Java Virtual Machine (JVM): Allotted to proce...
mapToLong()、mapToDouble()三个方法分别生成IntStream 、LongStream 、DoubleStream 三个接口类型的对象,这个方法的参数分别为3个函数式接口ToIntFunction、ToLongFunction、ToDoubleFunction,使用时可以用lambda表达式计算返回对应的int、long、double类型即可,简单看下这三个方法的源码(省略注释):...
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...

It is similar to the traditional for loop which takes a seed value, a condition, and an increment operation -for(int i = 1; i <= 10; i++). Conclusion Java 9 has done several improvements in existing APIs including Optional, Collection and Stream APIs. ...
