開始使用new Date()測試,並用通過date.getMonth(),和date.getDay()獲取,不過後來發現這兩個訪求是jdk1.1版本的,現在已經不用了,而且結果也不正確.

int month = (date.get(Calendar.MONTH))+1;
int day = date.get(Calendar.DAY_OF_MONTH); 

獲取當前的月份和日期

試了一下,果然正確

後來檢視java doc文件,MONTH欄位解釋如下

Field number for get and set indicating the month. This is a calendar-specific value. The first month of the year is JANUARY 

這個欄位的值只是說明get()的屬性欄位值,來獲取month的

以下為獲取其它:

Calendar CD = Calendar.getInstance();
int YY = CD.get(Calendar.YEAR) ;
int MM = CD.get(Calendar.MONTH)+1;
int DD = CD.get(Calendar.DATE);
int HH = CD.get(Calendar.HOUR);
int NN = CD.get(Calendar.MINUTE);
 
int SS = CD.get(Calendar.SECOND);
int MI = CD.get(Calendar.MILLISECOND);

Calendar cal = Calendar.getInstance();

        //當前年
        int year = cal.get(Calendar.YEAR);
        //當前月
        int month = (cal.get(Calendar.MONTH))+1;
        //當前月的第幾天：即當前日
        int day_of_month = cal.get(Calendar.DAY_OF_MONTH);
        
 
//當前時：HOUR_OF_DAY-24小時制；HOUR-12小時制
        int hour = cal.get(Calendar.HOUR_OF_DAY);
        //當前分
        int minute = cal.get(Calendar.MINUTE);
        //當前秒
        int second = cal.get(Calendar.SECOND);
        //0-上午；1-下午
        int ampm = cal.get(Calendar.AM_PM);
        //當前年的第幾周
        int week_of_year = cal.get(Calendar.WEEK_OF_YEAR);
        //當前月的第幾周
        int week_of_month = cal.get(Calendar.WEEK_OF_MONTH);
        //當前年的第幾天
        int day_of_year = cal.get(Calendar.DAY_OF_YEAR);
