How to use Arrays.sort () to find the maximum of Java
This article will explain in detail how Java uses Arrays.sort () to get the maximum value. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.
Rely on Arrays.sort () implementation
The array can be sorted from small to large according to the Arrays.sort method. After the sorting is completed, the value of the last bit is the maximum value. 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 = findMaxBySort (arr); / / find the maximum value based on Arrays.sort
System.out.println ("Max is:" + max)
}
/ * *
* find the maximum value based on Arrays.sort
* @ param arr Array to be queried
* @ return maximum
, /
Private static int findMaxBySort (int [] arr) {
Arrays.sort (arr)
Return arr [arr.length-1]
}
}
The results of the above procedures are as follows:
The maximum is: 7
