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\';

I agree with Petar Ivanov but it is best if we implement in following way:

public String replace(String str, int index, char replace){     
    if(str==null){
        return str;
    }else if(index<0 || index>=str.length()){
        return str;
    }
    char[] chars = str.toCharArray();
    chars[index] = replace;
    return String.valueOf(chars);       
}
