如何得到本周的周一和周七的日期？
如何得到上周的周一和周七的日期？
如何得到上月的第一天和最后一天的日期？

据说，java 基础类中有一个叫Calendar 的东东……

---

能给代码吗？那个我不怎么熟悉

---

如果你需要 zerobugforsoftware@163.com 联系

---

获得当天的DATE日期
Calendar.getInstance().get(Calendar.DAY_OF_MONTH)

今天是星期几
Calendar.getInstance().get(Calendar.DAY_OF_WEEK)

然后自己判断 后面没问题了吧~！ 接分

如何得到上月的第一天和最后一天的日期？

Calendar

---

上月最后一天用本月第一天-1天即可

Calendar的时间类型加减功能特别强大, 好好看看

---

Calendar.getInstance().get(int filed)..自己去设置...

.....接分

传说中的高手......

/**
* Get the date of monday in this week
*
* @return yyyy-MM-dd

public static String getMondayOfThisWeek() {
String strTemp = "";
Calendar c = Calendar.getInstance();
int dayofweek = c.get(Calendar.DAY_OF_WEEK) - 1;
if (dayofweek == 0)
dayofweek = 7;
c.add(Calendar.DATE, -dayofweek + 1);
strTemp = c.get(1) + "-";
if (c.get(2) + 1 < 10)
strTemp += "0";
strTemp = strTemp + (c.get(2) + 1) + "-";
if (c.get(5) < 10)
strTemp += "0";
strTemp += c.get(5);
return strTemp;
}

public static String getSundayOfThisWeek() {
String strTemp = "";

Calendar.getInstance().get(Calendar.DAY_OF_MONTH)//get Date
Calendar.getInstance().get(Calendar.DAY_OF_WEEK)//get week
