- Given an array of strings in java.
- We would like to sort an array of strings in alphabetical order using Java8 Lambda Stream.
Examples: Sort array of strings in alphabetical order
Example : Given an Input Array : [Java, Python, ReactJS, Angular, C#]Output of program should be [Angular, C#, Java, Python, ReactJS] |
Method to sort stream in natural order
| Method Name | Description |
|---|---|
| Stream<T> sorted() | Returns a stream consisting of the elements of this stream, sorted according to natural order. |
Algorithm: sort array of string in alphabetical order
- Given an array of string.
- Get Java 8 Stream using Arrays.stream method of Arrays class.
- Sort sequential stream using sorted method of stream.
- Collect sequential stream in array of strings.
- Print array of string using Arrays.toString method.
Code: sort array of string in alphabetical order – lambda stream
package org.learn.beginner;import java.util.Arrays;public class SortStringArray { public static void main(String[] args) { String [] arrString = {"Java", "Python", "ReactJS", "Angular", "C#"}; System.out.println("Input Array : "+ Arrays.toString(arrString)); arrString = Arrays.stream(arrString) .sorted() .toArray(String[]::new); System.out.println("Sorted Array : "+ Arrays.toString(arrString)); }} |
Output: sort array of string in alphabetical order
Input Array : [Java, Python, ReactJS, Angular, C#]Sorted Array : [Angular, C#, Java, Python, ReactJS] |
