Convert C# regex Code to Java -

i have found regex extractor code in c#. can tell me how works, , how write equivalent in java?

// extract songtitle metadata header.  // trim needed, because stations don't trim songtitle filename =      regex.match(metadataheader,        "(streamtitle=')(.*)(';streamurl)").groups[2].value.trim(); 

this should want.

// create regex pattern pattern p = pattern.compile("(streamtitle=')(.*)(';streamurl)"); // create matcher matches pattern against input matcher m = p.matcher(metadataheader); // if found match if (m.find()) {     // filename second group. (the `(.*)` part)     filename = m.group(2); }
