How to get the day of the week in java

The first method:

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

Second method: Use SimpleDateFormat to format the date

Date date = new Date();
SimpleDateFormat dateFm = new SimpleDateFormat("EEEE");
String currSun = dateFm.format(date);
System.out.println(currSun);

Note: The format string is case-sensitive
For the parameters passed in when creating SimpleDateFormat: EEEE represents the day of the week, such as "Thursday"; MMMM represents Chinese Month, such as "July"; MM represents the month, such as "07"; yyyy represents the year, such as "2017"; dd represents the day, such as "05"
