Replace First Occurrence Of Character In Android/java?

I would like to take the 's' out of http. https://joy.tothewor.ld/today/and/tommorrow http://joy.tothewor.ld/today/and/tommorrow What's the fastest/less expensive way? substrin

Solution 1:

String.replaceFirst will do the job.

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

Solution 2:

String.replaceFirst is heavyweight

publicStringreplaceFirst(String regex, String replacement) {
        returnPattern.compile(regex).matcher(this).replaceFirst(replacement);
 }

this is the fastest way

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

Solution 3:

You can try this

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