I have a class that has a big method that calls on a lot of private methods. I think I want to extract those private methods into their own classes for one because they contain business logic and I think they should be public so they can be unit tested.

Here's a sample of the code:

public void handleRow(Object arg0) {
    if (continueRunning){
        hashData=(HashMap<String, Object>)arg0;
        Long stdReportId = null;
        Date effDate=null;
        if (stdReportIds!=null){
            stdReportId = stdReportIds[index];
        }   
        if (effDates!=null){
            effDate = effDates[index];
        }
        initAndPutPriceBrackets(hashData, stdReportId, effDate);
        putBrand(hashData,stdReportId,formHandlerFor==0?true:useLiveForFirst);
        putMultiLangDescriptions(hashData,stdReportId);
        index++;
        if (stdReportIds!=null && stdReportIds[0].equals(stdReportIds[1])){
            continueRunning=false;
        }       
        if (formHandlerFor==REPORTS){
            putBeginDate(hashData,effDate,custId);
        }
        //handle logic that is related to pricemaps.
        lstOfData.add(hashData);
    }
}   

What design pattern should I apply to this problem?
