How to use Arrays.stream () to find the maximum of Java

This article is about how Java uses Arrays.stream () to maximize its value. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

Implement according to Arrays.stream ()

Stream is one of the new core features of JDK 8. Using it, we can easily implement many functions, such as finding the maximum and minimum values. The implementation code is as follows:

Import java.util.Arrays

Public class ArrayMax {

Public static void main (String [] args) {

Int [] arr = {3,7,2,1,-4}

Int max = findMaxByStream (arr); / / find the maximum value based on stream

System.out.println ("Max is:" + max)

}

/ * *

* find the maximum value based on stream

* @ param arr Array to be queried

* @ return maximum

, /

Private static int findMaxByStream (int [] arr) {

Return Arrays.stream (arr). Max (). GetAsInt ()

}

}

The results of the above procedures are as follows:

The maximum is: 7
