What's the fastest/less expensive way?

String.replaceFirst is heavyweight 

 public String replaceFirst(String regex, String replacement) {
        return Pattern.compile(regex).matcher(this).replaceFirst(replacement);
 }

this is the fastest way

str = str.substring(0, 4) + s.substring(5);

You can try this

String str="https://joy.tothewor.ld/today/and/tommorrow"
                                            .replace("https://","http://");

String.replaceFirst will do the job.

String output = input.replaceFirst("s","");
