Question

EDIT: I found the answer here. Returning the String found with a regular expression

Is there a straightforward way to get a list of all the substrings that match a regex within a string?

It should do something like this.

• Example string: Google
• Example regex: (og.e)
• What I want to obtain with this method: ogle

Another example.

• Example string: Facebook
• Example regex: (a.o)
  String I want to obtain with this method: acebo

EDIT: I’ve found something that might be relevant to this question. http://www.java2s.com/Tutorial/CSharp/0360__Regular-Expression/Matchindexandvalue.htm I still don’t know whether this will do what I want it to do.

Answer 1

You need to start learn/use java.util.regex API classes – Pattern and Matcher. For more info on regular expression read this tutorial.

Sample:

 Pattern pat=Pattern.compile("og.e");
 Matcher mat=pat.matcher("Google");
 if(mat.find())
     System.out.println(mat.start());
