Java取得日期时间的代码

使用SimpleDateFormat 来获取时间

        SimpleDateFormat dateFormat = new  SimpleDateFormat( " yyyyMMddHHmmss " );
        String date = dateFormat.format( new  Date()); 
         return  Long.parseLong(date);

使用Canlendar 类来取得时间

        Calendar time = Calendar.getInstance(); 
        time.setTime( new  Date( 1165991528156L ));
        
        System.out.println( " Year: " + time.get(Calendar.YEAR));
        System.out.println( " MONTH: " + time.get(Calendar.MONTH));
        System.out.println( " DATE: " + time.get(Calendar.DATE));
        System.out.println( " HOUR: " + time.get(Calendar.HOUR));
        System.out.println( " MINUTE: " + time.get(Calendar.MINUTE));
        System.out.println( " SECOND: " + time.get(Calendar.SECOND));
