Java - How to sort String in alphabetical order?

Introduction


In this post, we will learn the following two examples

a) Sort single String in alphabetical order
b) Sort array of Strings

Sort single String in alphabetical order


import java.util.Arrays;

public class SortStringAlphabetical {

 private static String inputString = "The quick brown fox jumps over the lazy dog";
 
 public static void main(String[] args) {
  System.out.println("Input String : " + inputString);
  
  char [] characters = inputString.toCharArray();
  Arrays.sort(characters);
  
  System.out.println("Alphabetical sorted String : " + new String(characters));
  
 }
}


Output

Input String : The quick brown fox jumps over the lazy dog
Alphabetical sorted String :         Tabcdeeefghhijklmnoooopqrrstuuvwxyz

Sort array of Strings



import java.util.Arrays;

public class SortStringArrayAlphabetical {

 private static String inputStrings[] = {"efg","xyz","abc"};
 
 public static void main(String[] args) {
  System.out.println("Input Strings : ");
  Arrays.stream(inputStrings).forEach(System.out::println);
  
  System.out.println("Sorted Array : ");
  Arrays.sort(inputStrings);
  
  Arrays.stream(inputStrings).forEach(System.out::println);
  
 }
}


Output

Input Strings : 
efg
xyz
abc
Sorted Array : 
abc
efg
xyz

Conclusion

In this tutorial, we learned how to sort a single string and array of strings in alphabetical order using Java language. Happy learning :)
