java - Replacing regex group results - is it possible? -

-

i want validate html link, plus @ same time extract "http/https", host , address part. possible change group 1 value, let's if "https" - output "true" value:

string url = "https://www.youtube.com/watch?v=1m9tjpltcw8   ";  pattern p = pattern.compile("^(?i)(https?)://(.{3,}?)/(.*?) *$");//(?i) - case insensitive matcher m = p.matcher(url); if (m.find()) {     system.out.println("g1: " + m.group(1));     system.out.println("g2: " + m.group(2));     system.out.println("g3: " + m.group(3)); }

the output is:

g1: https//but want replace - when "http" - "false", "https" - "true" g2: www.youtube.com g3: watch?v=1m9tjpltcw8

what about

g1 = "http".equals(m.group(1)) ? "false" : "true"

i've been working on making 2d map editor past 2 weeks or so, , i've run strange problem. trying optimize code, example, making functions should've been functions begin with, did made cpu usage go through roof. i've tried commenting out different sections of code thought culprits (scrolling, rendering, other calculations) no avail. think issue might trying call things within different functions, sake of making modular possible, i'd functionality. the other major change i've made since file i'm comparing i've ported variables external cpp file, since having variables global makes lot easier use within different functions. simple issue, can't life of me understand why happens. with original code, around 2-3% cpu usage. new code, around 20-35%, but, if move mouse around, it'll drop around 6-8%. tl;dr: after trying optimize code using functions, i've somehow killed performance, , found strange quirk moving mouse reduces cpu usage.. /...
