How to Sort a List in Descending Order in Java ?

Answer

To sort a list in descending order in Java, you can use the sort method along with a custom comparator.

✐ Examples

1 Sort a List of Integers in Descending Order

In this example,

We create a list named numbers with integer values.
We define a custom comparator that compares integers in descending order.
We call the sort method on the numbers list and pass the custom comparator to sort it in descending order.
Finally, we print the sorted list to the console.

Java Program

import java.util.Collections;
import java.util.List;
import java.util.Comparator;
import java.util.Arrays;

public class Main {
    public static void main(String[] args) {
        List<Integer> numbers = Arrays.asList(5, 2, 8, 1, 3);
        Collections.sort(numbers, Comparator.reverseOrder());
        System.out.println("Sorted list in descending order: " + numbers);
    }
}

Output

Sorted list in descending order: [8, 5, 3, 2, 1]

2 Sort a List of Strings in Descending Order

In this example,

We create a list named words with string values.
We define a custom comparator that compares strings in descending order based on length.
We call the sort method on the words list and pass the custom comparator to sort it in descending order.
Finally, we print the sorted list to the console.

Java Program

import java.util.Collections;
import java.util.List;
import java.util.Comparator;
import java.util.Arrays;

public class Main {
    public static void main(String[] args) {
        List<String> words = Arrays.asList("banana", "apple", "cherry");
        Collections.sort(words, Comparator.comparing(String::length).reversed());
        System.out.println("Sorted list in descending order: " + words);
    }
}

Output

Sorted list in descending order: [banana, cherry, apple]
