Shuffling a Word

[tulip ravine]

Hi I am trying to shuffle a word completely randomly and this is what I have done (using the fischer-yates method)

private static String scrambleWord(String randomWord) {
        /** Scrambles the random word chosen from the text file 
         * 
         * @param randomWord A string with the word randomly chosen from the list of words 
         * @return scrambledWord A string with the word chosen shuffled at random 
         */

        // Convert string to an array of characters 
        char[] wordArray = randomWord.toCharArray(); 

        Random random = new Random(); 

        // Start from last element and swap each time 
        for (int i = wordArray.length-1; i >= 0; i--) {

            // Pick a random index 
            int j = random.nextInt(i+1); 

            // Swap specific index with random index
            char letter = wordArray[i];
            wordArray[i] = wordArray[j];
            wordArray[j] = letter;  
        }

        String scrambledWord = String.valueOf(wordArray);  

        return scrambledWord; 

    }

However, sometimes I find that on the off chance this happens:

This seems to only be happening with three letter words like EGG and KEY

I think that what’s happening is the random scramble you’re getting is the same as the original word

There’s a 1/6 chance of that happening for 3 letter words

1/24 for four letters

Assuming a fully random scramble anyways

Yeah I tried to fix it like this in my main method

 // Scramble the chosen word 
        String scrambledWord = scrambleWord(chosenWord); 
        while (chosenWord.equals(scrambledWord)) {
            scrambledWord = scrambleWord(chosenWord); 
        } 

It seems not to give me any original words now

It was probably just scrambling to the original word, the only scrambles of pen are
PEN
ENP
NPE
NEP
EPN
PNE

Yeah I figured as much thank you!
