Question

I need a method that switches a letter from a specific index with another letter. Is there anything like it?

Like so:

String word = "test";
String letter = "e";
String secretWord = "????";

find the index of letter e and then find if e is in word. Then switch a “?” based on the index of the e in test.

So it would be ?e?? for secretWord.

Answer 1

        string word = "test";
        char letter = 'e';
        string secretWord = "????";
        int index = word.indexOf(letter);
        if(index >= 0)
        {
         secretWord = secretWord.substring(0,index)+letter+secretWord.substring(index + 1);
         System.out.println(secretWord);
        }
