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
    }
}
