java获取当前时间是星期几

public static String getWeek() {    String[] weekDays = {"星期日", "星期一", "星期二", "星期三", "星期四", "星期五", "星期六"};    Calendar mCalendar = Calendar.getInstance();    mCalendar.setTime(new Date());    int day = mCalendar.get(Calendar.DAY_OF_WEEK) - 1;    if (day < 0)        day = 0;    return weekDays[day];}

直接调用即可
