java - Only take URL Part from String -

i want url string can show url in webview.

example strings:

exp 1- hello dilip refer url www.google.com. exp 2- hi ramesh android http://android.com 

i want www.google.com , http://android.com how can split them out of string

assuming string below can use regex below extract www.google.com , http://android.com.

string s = "hello dilip refer url www.google.com. hi ramesh  android http://android.com";    pattern pc = pattern.compile("((http://)|(www.))[a-z,a-z]+.com"); matcher matcher = pc.matcher(s); while(matcher.find()) {    system.out.println("string extracted   "+matcher.group()); } 

output

string extracted   www.google.com string extracted   http://android.com  

note: above not work these kind of urls http://meta.stackoverflow.com ,www.google.co.uk , b3ta.com.

edit:

       string s = "hello dilip refer www.google.co.uk www.google.co.in url www.google.com. hi ramesh android http://android.com hello there meta.stackoverflow.com";           pattern pc = pattern.compile("((http://)|(www.))([a-z,a-z,0-9])+((.com)|(.co.[a-z]{2}))|([a-z,a-z,0-9].[a-z,a-z,0-9])+.com");        matcher matcher = pc.matcher(s);        while(matcher.find())        {           system.out.println("string extracted   "+matcher.group());        } 

output:

       string extracted   www.google.co.uk        string extracted   www.google.co.in        string extracted   www.google.com        string extracted   http://android.com        string extracted   meta.stackoverflow.com 

even above not perfect. if can modify above regex should you
