Question

我正在制定一项要求。我需要做的是从数据库中恢复最后的日期，增加它，然后检查一天是否是星期六。我坚持的部分是如何检查第二天是否是星期六我正在使用primefaces 3.5 jsf2.1 apache tomcat 7.0.39

FacesContext context = FacesContext.getCurrentInstance();
    Map requestMap = context.getExternalContext().getRequestParameterMap();
    String value = (String) requestMap.get("id");
    Integer id = Integer.parseInt(value);
    SimpleDateFormat sdf= new SimpleDateFormat();
    String sector=new String();
    setFund(new Fund());
    for(Map row:fund_grid){
        Integer edit_id=(Integer.parseInt((String) row.get("fund_id")));
        if(id.equals(edit_id)){
            sector=(String) row.get("fund_sector_label");
            mfp.setFund_id(Integer.parseInt( (String) row.get("fund_id")));
            fund.setFund_id( (String) row.get("fund_id"));
            setValidity_date(request_invoker.select_validity_date());
            try {
                Date ndate=sdf.parse((String) getValidity_date().get(0).get("validitydate"));

//日期在此处从数据库值15-11-2013退出

//现在递增一天

                Calendar c = Calendar.getInstance();
                c.setTime(ndate);
                c.add(Calendar.DATE, 1);
                fund.setNav_entry_date(c.getTime());

//这里是我被困的地方我不知道如何检查日期是否是星期六

            if(fund.getNav_entry_date().equals(Calendar.SATURDAY))
                {
                c.add(Calendar.DATE, 2);
                fund.setNav_entry_date(c.getTime());
                }
                else
                {
                    fund.setNav_entry_date(c.getTime());

                }
            } catch (ParseException e) {
                e.printStackTrace();
            }
        }
    }
    RequestContext context2 = RequestContext.getCurrentInstance();
    if(sector.equals("open-end")){

        context2.execute("opendialog.show();");
        }
    else if(sector.equals("close-end")){
        context2.execute("closedialog.show();");
        }
    else if(sector.equals("pension")){
        context2.execute("pensiondialog.show();");
        }

}

任何非常感谢的帮助

对bean进行了更改并且它正常工作日历c具有来自数据库的日期，而d具有当前日期。

Calendar c = Calendar.getInstance();
                c.setTime(ndate);

                Calendar d=Calendar.getInstance();  

                if(d.get(Calendar.DATE)==(c.get(Calendar.DATE)))
                {
                    //message here
                    FacesMessage msg = new FacesMessage("NAV Upto Date" , "NAV Upto Date");
                    FacesContext.getCurrentInstance().addMessage(null, msg);
                    break;
                }

                else
                {
                c.add(Calendar.DATE, 1);
                int day=c.SATURDAY;
                int week=c.get(Calendar.DAY_OF_WEEK);  
                if(day==(week))
                {
                c.add(Calendar.DATE, 2);
                fund.setNav_entry_date(c.getTime());
                mfp.getDc().setValiditydate(c.getTime());
                }
                else
                {
                    fund.setNav_entry_date(c.getTime());
                    mfp.getDc().setValiditydate(c.getTime());   
                }
                RequestContext context2 = RequestContext.getCurrentInstance();
                if(sector.equals("open-end")){

                    context2.execute("openenddialog.show();");
                    }
                else if(sector.equals("close-end")){
                    context2.execute("closeenddialog.show();");
                    }
                else if(sector.equals("pension")){
                    context2.execute("pensiondialog.show();");
                    }
            }

第二天使用日历JSF primefaces进行检查
