Hello. In this tutorial, we will explain the most commonly used Java 8 Stream APIs: the forEach() and filter() methods. 1. Introduction Before diving deep into the practice stuff let us understand the forEach and filter methods. 1.1 forEach method This method is used to iterate the eleme...
7.We add elements to Collection object only after it is computed completely.We can add elements to Stream Object without any prior computation. That means Stream objects are computed on-demand. 8.We can iterate and consume elements from a Collection Object at any number of times.We can iterat...

Consider, for a moment, the Iterator interface. Currently, it has three methods (hasNext, next, and remove), and each must be defined. But an ability to “skip” the next object in the iteration stream might be helpful. And because the Iterator’s implementation is easily defined in terms...
However, if you’re doing CPU-intensive operations, there’s no point in having more threads than processors, so go for a parallel stream, as it is easier to use. Reference: Java 8: CompletableFuture vs Parallel Stream from our JCG partner Fahd Shariff at the fahd.blog blog....
