HI iwant to change .xls java code to suport new version .xlsx

and my .xls code is

public class ExcellGprs {

public static void main(String[] args) {
    Connection con = null;
    PreparedStatement st = null;
    ResultSet rs = null;
    try {

        String strXMLFile = "ExcellGprs.xml";
        if (args != null && args.length > 1) {
            strXMLFile = args[1];

}
