how can i identify some folders and ignore others?

Following on from my previous question of counting files and folders, i need to isolate particular folder names and how many file are within, such as foldername/number of files has this many items, second folder has this many. thanks

here is the previous code i am working with:

<%@page import="java.io.*, javax.servlet.jsp.JspWriter" %>
<%!
int listDir( JspWriter out, File dir ) throws IOException {
    File[] files = dir.listFiles();
    int subCount = 0;
    for( int ii=0, end=files.length; ii < end; ii++ )
         if( files[ii].isDirectory() ) subCount += listDir( out, files[ii] );
    int count = 0;
    out.println( dir.getPath() );
    out.println( "<ul>" );
    for( int ii=0, end=files.length; ii < end; ii++ ) {
         if( files[ii].isFile() ) {
              out.println( "<li>"  + files[ii].getName() + "</li>" );
              count++;
         }
    }
    out.print( "<p>total: " + (count+subCount) + " files" );
    if( subCount > 0 ) out.print(", " + count + " in this dir, " + subCount +" in subdirs" );
    out.println( ".</ul>" );
    return subCount + count;
}
%>
<%
    String path = application.getRealPath( "/" );
    File dir = new File( path );
    listDir( out, dir );
%>
