Hello guys, if you want to learn about Intstream in Java 8 and looking for a simple tutorial and example then you have come to the right place. Earlier, I have shared 10 examples of Lambda expression and filter+ map+ collect examples and in this article, I will show you how to use IntStream in Java 8. IntStream is a specialization of Stream class for primitive int values. It allows you to perform a sequential and parallel aggregate operation on a list of values like count() to print the total number of element in stream, min() to find minimum value in the stream, max() to find maximum value in the stream, sum() to find a total of all values and average() to find the average of all numbers in the stream.
