How to Sort an Array in Descending Order in Java - Step by Step Examples

How to Sort an Array in Descending Order in Java ?

Answer

To sort an array in descending order in Java, you can use the `Comparator.reverseOrder()` method for both arrays of integers and arrays of strings.

✐ Examples

1 Sort Array of Integers in Descending Order

In this example,

Create an array of integers, for example, numbers.
Use the Comparator.reverseOrder() method along with Arrays.sort() to sort the array of integers in descending order.
Print the sorted array to see the result.

Java Program

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

public class Main {
    public static void main(String[] args) {
        Integer[] numbers = {5, 2, 8, 1, 9};
        Arrays.sort(numbers, Comparator.reverseOrder());
        System.out.println(Arrays.toString(numbers));
    }
}

Output

[9, 8, 5, 2, 1]

2 Sort Array of Strings in Descending Order

In this example,

Create an array of strings, for example, words.
Use the Comparator.reverseOrder() method along with Arrays.sort() to sort the array of strings in descending order.
Print the sorted array to see the result.

Java Program

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

public class Main {
    public static void main(String[] args) {
        String[] words = {"apple", "banana", "cherry", "date"};
        Arrays.sort(words, Comparator.reverseOrder());
        System.out.println(Arrays.toString(words));
    }
}

Output

[date, cherry, banana, apple]
