How do you change the order of a string in Java?

Procedure:

  1. Convert input string to Character array. There is no direct method to do it. We will use for loop to fill the array.
  2. Use Arrays. sort(T [ ], Comparator c) method to sort Character array.
  3. Now we can use StringBuilder to convert the Character array to String.

How do you reverse a substring order?

Strings can be reversed using slicing. To reverse a string, we simply create a slice that starts with the length of the string, and ends at index 0. The slice statement means start at string length, end at position 0, move with the step -1 (or one step backward).
