public class DateTest {  
  
    public static void main(String[] args) throws ParseException {  
        Calendar now = Calendar.getInstance();  
        System.out.println("年: " + now.get(Calendar.YEAR));  
        System.out.println("月: " + (now.get(Calendar.MONTH) + 1) + "");  
        System.out.println("日: " + now.get(Calendar.DAY_OF_MONTH));  
        System.out.println("时: " + now.get(Calendar.HOUR_OF_DAY));  
        System.out.println("分: " + now.get(Calendar.MINUTE));  
        System.out.println("秒: " + now.get(Calendar.SECOND));  
        System.out.println("当前时间毫秒数：" + now.getTimeInMillis());  
        System.out.println(now.getTime());  
  
        Date d = new Date();  
        System.out.println(d);  
        SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");  
        String dateNowStr = sdf.format(d);  
        System.out.println("格式化后的日期：" + dateNowStr);  
          
        String str = "2012-1-13 17:26:33";  //要跟上面sdf定义的格式一样  
        Date today = sdf.parse(str);  
        System.out.println("字符串转成日期：" + today);  
    }  
}
