Replace a character at a specific index in a string?

Question

I\'m trying to replace a character at a specific index in a string.

What I\'m doing is:

String myName = \"domanokz\";
myName.charAt(4) = \'x\';
         


        

Answer 1

Turn the String into a char[], replace the letter by index, then convert the array back into a String.

String myName = "domanokz";
char[] myNameChars = myName.toCharArray();
myNameChars[4] = 'x';
myName = String.valueOf(myNameChars);
