import java.util.Arrays;

// Main class containing the entry point of the program
public class Main {
    public static void main(String[] args) {
        // Step 1: Declare and initialize an Integer array (wrapper type)
        Integer[] numbers = {5, 1, 9, 3, 7};
        System.out.println("Original array: " + Arrays.toString(numbers));

        // Step 2: Sort the Integer array in descending order
        // Collections.reverseOrder() provides a Comparator for reverse sorting
        Arrays.sort(numbers, Collections.reverseOrder());

        // Step 3: Print the array after sorting
        System.out.println("Array sorted descending: " + Arrays.toString(numbers));
