该代码段展示了一个Java方法，用于获取指定年份一整年的周六和周日日期，并将它们存储到Map中，包括日期字符串和星期标识。方法首先初始化一个Calendar实例，然后遍历该年所有日期，判断是否为周末并添加到结果列表中。

   //获取一年的双休日
    public void scsxr() throws  Exception {
        List<Map<String, String>> list = new ArrayList();
        List list1 = new ArrayList();
        final SimpleDateFormat sdf = new SimpleDateFormat("yyyyMMDD");
        Calendar cdl = Calendar.getInstance(Locale.CHINA);
        int nextyear = cdl.get(Calendar.YEAR);
        cdl.set(nextyear, 0, 1);
        for (int day = 1; day <= cdl.getActualMaximum(Calendar.DAY_OF_YEAR); day++) {
            cdl.set(Calendar.DAY_OF_YEAR, day);
            int weekday = cdl.get(Calendar.DAY_OF_WEEK);
            if (weekday == Calendar.SATURDAY || weekday == Calendar.SUNDAY) {
                list1.add(cdl.get(Calendar.YEAR));
                Map map = new HashMap();
                map.put("sj", sdf.format(cdl.getTime()));
                if (weekday == Calendar.SATURDAY) {
                    map.put("bz", "星期六");

                } else {
                    map.put("bz", "星期天");
                }
            }

        }
        for (Map map:list) {
            int str=;
            TDcJjrsjgl tdcJjrsjgl=new TDcJjrsjgl();
            TDcJjrsjgl.setSj(map.put("sj").toString());
            TDcJjrsjgl.setBz(map.put(bz).toString());
            tdcJjrsjgl.setNf(list.get(str++).toString();
         

    }
