Find Maximum and Minimum Numbers is an Array

Back to: Java Tutorials

To find the maximum and minimum value in an array of integers in Java, you can use a for loop to iterate over the array and compare each element to the current maximum and minimum values. Here is an example:

public class MaxMinExample {
    public static void main(String[] args) {
        int[] numbers = {2, 5, 8, 1, 9, 3};
        int max = numbers[0];
        int min = numbers[0];
        for (int i = 1; i < numbers.length; i++) {
            if (numbers[i] > max) {
                max = numbers[i];
            }
            if (numbers[i] < min) {
                min = numbers[i];
            }
        }
        System.out.println("Maximum value in array: " + max);
        System.out.println("Minimum value in array: " + min);
    }
}

In this code, we define an array of integers numbers with values of {2, 5, 8, 1, 9, 3}. We then define two variables max and min, initialized to the first element of the array. We use a for loop to iterate over the array, comparing each element to the current max and min values. If an element is greater than the current max, we update max. If an element is less than the current min, we update min. Finally, we print the max and min values to the console.

The output of this code is:

Maximum value in array: 9
Minimum value in array: 1

Using built-in Method

To find the maximum and minimum value in an array of integers in Java, you can use the Arrays class from the java.util package. Here is an example:

import java.util.Arrays;

public class MaxMinExample {
    public static void main(String[] args) {
        int[] numbers = {2, 5, 8, 1, 9, 3};
        int max = Arrays.stream(numbers).max().getAsInt();
        int min = Arrays.stream(numbers).min().getAsInt();
        System.out.println("Maximum value in array: " + max);
        System.out.println("Minimum value in array: " + min);
    }
}
