How to find the k biggest values from an array in Java

Answer 1

import java.util.Arrays;

public class MaxKElements {
    public static int[] maxSumOfK(int[] arr, int k) {
        Arrays.sort(arr);
        int[] result = new int[k];

        for (int i = 0; i < k; i++) {
            result[i] = arr[arr.length - 1 - i];
        }

        return result;
    }

    public static void main(String[] args) {
        int[] arr = {11, 2, 4, 9, 3, 6, 5, 1};
        int k = 3;

        System.out.println(Arrays.toString(maxSumOfK(arr, k)));
    }
}
