Extract a string within a string

Question

How can I access WWW.GOOGLE.COM within this String.

I can use the substring method to chop off javascript:linkToExternalSite(' but how can I remove the subsequest string.

So that

javascript:linkToExternalSite('WWW.GOOGLE.COM','D','SDFSDX2131D','R','','X','D','DFA','SAFD')

becomes

WWW.GOOGLE.COM

This works

string = string.substring(31, string.length());
string = string.substring(0, string.indexOf("'"));

The format of linkToExternalSite is always same or it may be change the format. — subodh

If myString = "www.google.com','..."

You could do:

result = myString.substring(0, myString.indexof("'");

You don't need to, there is an easier way:

final String it = "WWW.GOOGLE.COM";

No need for chop, cut or other bloody operations.

How is this supposed to work, are you not extracting this string by just looking at it yourself ?

You said you want to extract that from the more complex string above - yet what I've shown is there is an easier way to get the string "WWW.GOOGLE.COM"

Use regex

String substring = //YOURSUBSTRING
    Pattern p = Pattern.compile("[W]{3}[.A-Z]+[.COM|.CO.UK]", Pattern.CASE_INSENSITIVE);

    Matcher matcher = p.matcher(substring);

        if (matcher.find()){
            String Url = matcher.group();
            System.out.println(matcher.group());

        }
