Solution using localeCompare
The first option to sort properly an array of strings, is to provide as comparator the localeCompare method of a string, this method returns a number indicating whether a reference string comes before or after or is the same as the given string in sort order. For example:
Solution using Intl.Collator

How to Sort an Array of Strings in JavaScript

How to sort strings in descending order?
You can use any comparison function you want with .sort (), so in this case we’d just need to swap the a and b to create a descending (Z-A) sort.
Using loop
The basic way of any sorting is to use loops. We will use two for loops and both will run one inside another. The outer loop will pick one by one element from the left of the string and the inner loop will compare it with all other elements to the left of it.
Sorting without using a loop
Instead of using two for loops, we can also sort the character array directly like below :
Using a comparator
We can improve the above program to compare all uppercase and lowercase characters as below :
Conclusion
We have seen four different ways to sort the characters in a string in Java. Actually, the second and third methods are the same. You can use the third one instead of the second one to support all uppercase and lowercase letters. It is up to your requirement which method you want to use.
