How to get this substring?

"C:\ViaSafe\Channel/boaTest/BoaFromExtract/report/done/1151076810520.0@BoaFromExtract.boaTest.A6.txt.ExtractReport.pdf"

The above is a string which I want to get the "A6.txt" out of it, the substring after it ".ExtractReport.pdf" and the string before it "@BoaFromExtract.boaTest." will always be constant.  However, the A6.txt can varies in size as I can have A12312321.txt, B23424.txt ect......

I know this has to do with Substring manipulation and trimming my string but I can not seem to come up with a clean method to do it, please help.

Thanks.

btw I store the orignal string in a String array.

           Pattern p = Pattern.compile("BoaFromExtract\\.boaTest\\.(.+)\\.ExtractReport\\.pdf");
            Matcher m = p.matcher("C:\\ViaSafe\\Channel/boaTest/BoaFromExtract/report/done/1151076810520.0@BoaFromExtract.boaTest.A6.txt.ExtractReport.pdf");
            m.find();
            System.out.println(m.group(1));

Tried to run this but the compile method does not seem to work, I check for Patter.method in my IDE but could not see compile either.

have you imported java.util.regex.* ?

I had import import java.util.regex.Matcher; only before
but eafter I put in import java.util.regex.*; then i still get the same error.

Focus on error gives me : The method compile(ClassGenerator, MethodGenerator) in the type Expression is not applicable for
 the arguments (String)


Sorry I am quite new to this Pattern so I am kind of clueless.

try
java.util.regex.Pattern p = java.util.regex.Pattern.compile("BoaFromExtract\\.boaTest\\.(.+)\\.ExtractReport\\.pdf");
