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>
}
