小视频源码，判断选择的日期是否是今天、本周、本月实现相关的代码

public static boolean isThisWeek(long time) {
        Calendar calendar = Calendar.getInstance();
        int currentWeek = calendar.get(Calendar.WEEK_OF_YEAR);
        calendar.setTime(new Date(time));
        int paramWeek = calendar.get(Calendar.WEEK_OF_YEAR);
        if(paramWeek==currentWeek){
           return true;
        }
        return false;
    }
**//判断选择的日期是否是今天**
 public static boolean isToday(long time)
    {
       return isThisTime(time,"yyyy-MM-dd");
    }
//判断选择的日期是否是本月
 public static boolean isThisMonth(long time)
    {
         return isThisTime(time,"yyyy-MM");
    }
 private static boolean isThisTime(long time,String pattern) {
        Date date = new Date(time);
         SimpleDateFormat sdf = new SimpleDateFormat(pattern);
         String param = sdf.format(date);//参数时间
         String now = sdf.format(new Date());//当前时间
         if(param.equals(now)){
           return true;
         }
         return false;
    }
