iam trying to get the my config to use placeholders but i keep on getting nullpointers Here is part of my code Code (Text): public String formatTime(double seconds) { int Sec = (int) (seconds % 60); int Min = (int) Math.floor(seconds / 60) % 60; int Hour = (int) Math.floor(seconds / 3600) % 24; int Day = (int) Math.floor(seconds / 86400); String sConfig = getConfig().getString("Seconds"); sConfig = sConfig.replaceAll("%s%", Sec + ""); sConfig = sConfig.replaceAll("%m%", Min + ""); sConfig = sConfig.replaceAll("%h%", Hour + ""); sConfig = sConfig.replaceAll("%d%", Day + ""); String mConfig = getConfig().getString("Minuties"); mConfig = mConfig.replaceAll("%s%", Sec + ""); mConfig = mConfig.replaceAll("%m%", Min + ""); mConfig = mConfig.replaceAll("%h%", Hour + ""); mConfig = mConfig.replaceAll("%d%", Day + ""); String hConfig = getConfig().getString("Hours"); hConfig = hConfig.replaceAll("%s%", Sec + ""); hConfig = hConfig.replaceAll("%m%", Min + ""); hConfig = hConfig.replaceAll("%h%", Hour + ""); hConfig = hConfig.replaceAll("%d%", Day + ""); String dConfig = getConfig().getString("Days"); dConfig = dConfig.replaceAll("%s%", Sec + ""); dConfig = dConfig.replaceAll("%m%", Min + ""); dConfig = dConfig.replaceAll("%h%", Hour + ""); dConfig = dConfig.replaceAll("%d%", Day + ""); String output = ""; if (seconds > 86399 ) output = dConfig; else if (seconds > 3599 ) output = hConfig; else if (seconds > 59) output = mConfig; else output = sConfig; return output; } public boolean onCommand(CommandSender sender, Command command, String label, String[] args) { if (command.getName().equalsIgnoreCase("formattime")) { player.sendMessage(formatTime((int)Double.parseDouble(args[0]))); return true; } }
where do you receive the error? Maybe is "getConfig()" null? Would be good to post the error line that appeared ( or just the full error also )

Ok so your error appeared in the first line: Code (Text): String sConfig = getConfig().getString("Seconds"); sConfig = sConfig.replaceAll("%s%", Sec + ""); So that basically means that getConfig() is null or your String in the config is null.
Its probably the string in my config is null cos my config is not updating to the new one I have now fixed the problem i didn't put the "" around the thing in the config Thank you for your help
