        //設置年份
        cal.set(Calendar.YEAR, year);
        //設置月份
        cal.set(Calendar.MONTH, month );
        cal.set(Calendar.DAY_OF_MONTH,  0);
        cal.set(Calendar.HOUR_OF_DAY, cal.getActualMaximum(Calendar.HOUR_OF_DAY));
        cal.set(Calendar.MINUTE, cal.getActualMaximum(Calendar.MINUTE));
        cal.set(Calendar.SECOND, cal.getActualMaximum(Calendar.SECOND));
