Java 8 Stream - Sort List of String objects in Ascending Order Example

In this source code example, we will use Java 8 stream API to sort a List of string objects in ascending order with an example.

Sort List of String objects in Ascending order using Java 8 Stream APIs

This example demonstrates different ways to sort List of String objects in Ascending order using Java 8 Stream APIs:

import java.util.ArrayList;

import java.util.Comparator;
import java.util.List;
import java.util.stream.Collectors;

public class StreamListSorting {
    public static void main(String[] args) {

        List < String > fruits = new ArrayList < String > ();
        fruits.add("Banana");
        fruits.add("Apple");
        fruits.add("Mango");
        fruits.add("Orange");

        List < String > sortedList = fruits.stream().sorted(Comparator.naturalOrder()).collect(Collectors.toList());
        System.out.println(sortedList);

        List < String > sortedList1 = fruits.stream().sorted((o1, o2) - > o1.compareTo(o2)).collect(Collectors.toList());
        System.out.println(sortedList1);

        List < String > sortedList2 = fruits.stream().sorted().collect(Collectors.toList());
        System.out.println(sortedList2);
    }
}

Output:

[Apple, Banana, Mango, Orange]
[Apple, Banana, Mango, Orange]
[Apple, Banana, Mango, Orange]
