How to get the day of the week of the current date in java

java Gets the day of the week at the current time:

 /**
     * 获取当前日期是星期几<br>
     * 
     * @param dt
     * @return 当前日期是星期几
     */
    public static String getWeekOfDate(Date dt) {
        String[] weekDays = {"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(dt);
        int w = cal.get(Calendar.DAY_OF_WEEK) - 1;
        if (w < 0)
            w = 0;
        return weekDays[w];
    }

The Calendar.getInstance() method can get the current date and time.

Calendar.DAY_OF_WEEK actually means: the day of the week, so it will be affected by the day of the week the first day is.
Some areas use Sunday as the first day of the week

yyyy represents the year, such as "2017"; dd represents the day, such as "28"
