String[] weeks = {"星期日","星期一","星期二","星期三","星期四","星期五","星期六"};
        Calendar cal = Calendar.getInstance();
        cal.setTime(new Date());
        System.out.println(cal.get(Calendar.DAY_OF_WEEK));
        int week_index = cal.get(Calendar.DAY_OF_WEEK) - 1;
        if(week_index<0){
        week_index = 0;
        }
        System.out.println(weeks[week_index]);

输出的结果如下：
