Verify if a String is a valid Url

How to use it.md

It's very simple to use:

Boolean isValid = isUrl("http://androcode.es");

Url_Validation.java

private static boolean isUrl(String s) {
    String regex = "^(https?://)?(([\\w!~*'().&=+$%-]+: )?[\\w!~*'().&=+$%-]+@)?(([0-9]{1,3}\\.){3}[0-9]{1,3}|([\\w!~*'()-]+\\.)*([\\w^-][\\w-]{0,61})?[\\w]\\.[a-z]{2,6})(:[0-9]{1,4})?((/*)|(/+[\\w!~*'().;?:@&=+$,%#-]+)+/*)$";
 
    try {
        Pattern patt = Pattern.compile(regex);
        Matcher matcher = patt.matcher(s);
        return matcher.matches();
 
    } catch (RuntimeException e) {
        return false;
    }
}
