Shifting characters within a string

``` String newStr; public RandomCuriosity(String input){ newStr = input; } public void shiftChars(){ char[] oldChar = newStr.toCharArray(); char[] newChar = new char[oldChar.length]; newChar[0] = oldChar[oldChar.length-1]; for(int i = 1; i < oldChar.length; i++){ newChar[i] = oldChar[i-1]; } newStr = String.valueOf(newChar); } ``` I created a method that shifts characters forward by one. For example, the input could be: The input: `Stackoverflow` The output: `wStackoverflo` How I did it is I mutated an instance of a string. Convert that string to a `char` array (calling it `oldChar`), assigned the last index of of `oldChar` as the first index of `newChar`, and made a for-loop that took the first index of `oldChar` as the second index of my new `Char` array and so forth. Lastly, I converted the char array back to a string. I feel like I did way too much to do something very simple. Is there a more efficient way to do something like this? EDIT Thanks for the great answers!
