How to Sort a List in Ascending Order in Java ?

Answer

To sort a list in ascending order in Java, you can use the Collections.sort() method or the List.sort() method.

✐ Examples

1 Sort a List of Integers in Ascending Order

In this example,

We create a list named numbers and initialize it with integer values.
We call the Collections.sort() method with the numbers list to sort it in ascending order.
The sort() method sorts the elements in place, modifying the original list.
Finally, we print the sorted list to the console.

Java Program

import java.util.*;

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

Output

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

2 Sort a List of Strings in Ascending Order

In this example,

We create a list named words and initialize it with string values.
We call the Collections.sort() method with the words list to sort it in ascending order.
The sort() method sorts the elements in place, modifying the original list.
Finally, we print the sorted list to the console.

Java Program

import java.util.*;

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

Output

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