[java] Java Array Sort descending?

This worked for me:

package doublearraysort;

import java.util.Arrays;
import java.util.Collections;

public class Gpa {


    public static void main(String[] args) {
        // initializing unsorted double array
        Double[] dArr = new Double[] {                 
            new Double(3.2),
            new Double(1.2),
            new Double(4.7),
            new Double(3.3),
            new Double(4.6),
           };
        // print all the elements available in list
        for (double number : dArr) {
            System.out.println("GPA = " + number);
        }

        // sorting the array
        Arrays.sort(dArr, Collections.reverseOrder());

        // print all the elements available in list again
        System.out.println("The sorted GPA Scores are:");
        for (double number : dArr) {
            System.out.println("GPA = " + number);
        }
    }
}

Output:

GPA = 3.2
GPA = 1.2
GPA = 4.7
GPA = 3.3
GPA = 4.6
The sorted GPA Scores are:
GPA = 4.7
GPA = 4.6
GPA = 3.3
GPA = 3.2
GPA = 1.2
