# Java - max value in array

0 points

This article will show you how to find the maximum value in an array in Java.

Quick solution:

``````Integer[] numbersArray = { 1, 5, 2, 16, -5};

int max = Collections.max(Arrays.asList(numbersArray));
System.out.println( max ); // 16``````

## Practical examples

1. With `Collections.max` method

``````public class MathExample {

public static void main(String[] args) {
Integer[] numbersArray = { 1, 5, 2, 16, -5};

int max = Collections.max(Arrays.asList(numbersArray));
System.out.println( max ); // 16
}
}``````

### 2. By comparing all the elements in the array

``````public class MathExample {

static double max(double[] array) {
double result = Double.NEGATIVE_INFINITY;
for (double currentNumber : array) {
if (result < currentNumber) result = currentNumber;
}
return result;
}

public static void main(String[] args) {
double[] numbersArray = {1.4, 5.0, 2.2, 16.0, -5.0};

System.out.println(  max(numbersArray) ); // 16.0
}
}``````
