public class DateUtil {

    public static String getDateFromISO(String isoDate){
        DateFormat sdf = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ssZ");
        DateFormat sd=new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
        try {
            return sd.format(sdf.parse(isoDate));
        } catch (ParseException e) {
            e.printStackTrace();
            return null;
        }
    }

    public static void main(String[] args) {
        System.out.println(DateUtil.getDateFromISO("2014-07-11T14:47:04+0800"));
    }
}
