How to sort an int array in descending order with Java

Answer 1

import java.util.Arrays;
import java.util.Comparator;

public class MyClass {
    public static void SortIntArrayInDescendingOrder(int[] array) {
        Arrays.sort(array);
        
        int length = array.length;
        
        for (int i = 0; i < length / 2; i++) {
            int temp = array[i];
            array[i] = array[length - 1 - i];
            array[length - 1 - i] = temp;
        }
    }
    
    public static void main(String args[]) {
        int[] array = {4, 2, 0, 9, 1, 5};
        
        SortIntArrayInDescendingOrder(array);

        System.out.println(Arrays.toString(array));  
    }
}
