java中关于时间的一些方法

1 获得当前时间   
private static String getCurTime() {
        Calendar cal = Calendar.getInstance();
        DateFormat sdf = new SimpleDateFormat ("yyyyMMddHHmmss");
        String strCurrTime = sdf.format(cal.getTime());
        return strCurrTime;
    }

2 获得当前月份的天数
    private int getDayOfMonth(int year, int month) {
        Calendar calendar2 = new GregorianCalendar(year, month, 0);
        return calendar2.getActualMaximum(Calendar.DAY_OF_MONTH);
    }

可以再简单一点点

    private static String getCurTime() { 
        DateFormat sdf = new SimpleDateFormat ("yyyyMMddHHmmss"); 
        String strCurrTime = sdf.format(new Date()); 
        return strCurrTime; 
    }
