获得日期中的月份

/** 判断是否为同一月份 */

   public boolean compareMonths(Date rechargeDate,Date date){

      Calendar c = Calendar.getInstance();

      c.setTime(rechargeDate);

      int rechargeMonth = c.get(Calendar.MONTH) + 1;//返回的是月份数字

      Calendar c1 = Calendar.getInstance();

      c1.setTime(new Date());

      int month = c1.get(Calendar.MONTH) + 1; //如果今天是2016/7/7，month=7

      return rechargeMonth==month?true:false;

   }

 

示例 说明：：：：：：：：：：：：

Calendar cal = Calendar.getInstance();
cal.setTime(new Date());
int month = cal.get(Calendar.MONTH); //注意月份是从0开始的,比如当前7月，获得的month为6，所以上面的方法给+1

示例：：：：：：：：：：：

 

 Calendar cal = Calendar.getInstance();
         int day = cal.get(Calendar.DATE);
         int month = cal.get(Calendar.MONTH) + 1;
         int year = cal.get(Calendar.YEAR);
         int dow = cal.get(Calendar.DAY_OF_WEEK);
         int dom = cal.get(Calendar.DAY_OF_MONTH);
         int doy = cal.get(Calendar.DAY_OF_YEAR);
  
         System.out.println("Current Date: " + cal.getTime());
         System.out.println("Day: " + day);
         System.out.println("Month: " + month);
         System.out.println("Year: " + year);
         System.out.println("Day of Week: " + dow);
         System.out.println("Day of Month: " + dom);
         System.out.println("Day of Year: " + doy);

 

下面是例子的输出：

Current Date: Thu Dec 29 13:41:09 ICT 2005

Day: 29

Month:12

Year:2005

Day of Week: 5

Day of Month:29
