计算当前日期的下一天

/**
* 找到日期date的后一天
* @author mrsir
* @param date
* @return date
*/
public static Date getLaterDay(Date date) {
        Calendar calendar = Calendar.getInstance();
        calendar.setTime(date);
        calendar.add(Calendar.DAY_OF_MONTH, 1);
        date = calendar.getTime();
        return date;
    }

判断给定日期是否是月末的一天

/**
     * 判断给定日期是否为月末的一天
     * @author mrsir
     * @param date
     * @return true:是|false:不是
     */
public static boolean isLastDayOfMonth(Date date) {
     Calendar calendar = Calendar.getInstance();
     calendar.setTime(date);
     calendar.set(Calendar.DATE, (calendar.get(Calendar.DATE) + 1));
     if (calendar.get(Calendar.DAY_OF_MONTH) == 1) {
         return true;
     }
     return false;
}

测试例子：

<p>public class ceshiDateLixiao {</p><p> /**  * @param args  */ @SuppressWarnings("deprecation") public static void main(String[] args) {    SimpleDateFormat sdf=new SimpleDateFormat("yyyy-MM-dd");//小写的mm表示的是分钟    String dstr="2008-8-31";    java.util.Date date = null;  try {   date = sdf.parse(dstr);  } catch (ParseException e) {   // TODO Auto-generated catch block   e.printStackTrace();  }       boolean flag = ceshiDateLixiao.isLastDayOfMonth(date);  System.out.println(flag);</p><p> } public static boolean isLastDayOfMonth(Date date) {      Calendar calendar = Calendar.getInstance();      calendar.setTime(date);      calendar.set(Calendar.DATE, (calendar.get(Calendar.DATE) + 1));      if (calendar.get(Calendar.DAY_OF_MONTH) == 1) {          return true;      }      return false;  } </p><p>}</p>
