System.out.println(c.get(Calendar.MONTH));
System.out.println(c.get(Calendar.DAY_OF_MONTH));
System.out.println(c.get(Calendar.DAY_OF_WEEK));
c.set(Calendar.YEAR ,3000);
System.out.println(getWeek(c));

private static String getWeek(Calendar c) {
String []str={"星期一","星期二", "星期三","星期四","星期五","星期六","星期天"};
