How to find the maximum value through cyclic comparison by Java
This article will explain in detail how to find the maximum value of Java through cyclic comparison. The editor thinks it is very practical, so I share it with you for reference. I hope you can get something after reading this article.
Cyclic contrast
The execution flow of the loop comparison is shown in the following figure:
As you can see from the above figure, the core of circular comparison is to define a maximum value, and then cycle through each element. If the value of the element is greater than the maximum value, update the maximum value to the value of this element, and then make the next comparison. We can find the maximum value until the end of the loop. The implementation code is as follows:
Public class ArrayMaxTest {
Public static void main (String [] args) {
Int [] arr = {3,7,2,1,-4}
Int max = findMaxByFor (arr); / / find the maximum
System.out.println ("Max is:" + max)
}
/ * *
* find the maximum value through the for loop
* @ param arr Array to be queried
* @ return maximum
, /
Private static int findMaxByFor (int [] arr) {
Int max = 0; / / maximum
For (int item: arr) {
If (item > max) {/ / the current value is greater than the maximum value and is assigned to the maximum value
Max = item
}
}
Return max
}
}
The results of the above procedures are as follows:
The maximum is: 7
