Regex: Simplify parameters of a java method (java.lang.String, xyz.Clazz -> String, Clazz) -


i need simple regex. goal simplify parameters of java method.

input: java.util.locale arg0, java.lang.string arg1, java.lang.object... arg2

output: locale arg0, string arg1, object... arg2

this how started, regex doesn't work yet.

pattern regex = pattern.compile("([a-z].*?)[a-z]", pattern.dotall); string str = "java.util.locale arg0, java.lang.string arg1, java.lang.object... arg2"; // replace groups (java.util., java.lang.) empty string // system.out.println(regex.matcher(str).replaceall(""));

how can that?

the following prints locale arg0, string arg1, object... arg2:

pattern regex = pattern.compile("(\\w+\\.(?=\\w))+"); string str = "java.util.locale arg0, java.lang.string arg1, java.lang.object... arg2"; system.err.println(regex.matcher(str).replaceall(""));

the regex match last dot such following character (not consumed regex, due lookahead), word character, e.g. letter. means works varargs, because have object... dot followed dot, rather word character.

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } &l
