怎么生成 2000年2月29日 的日期？

Question

我刚查了API，原因，它要加减 1900 年那么，生成与分解指定的日期，究竟用什么方法好？Date.getYear() 会减1900年

Answer 1

SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
try {
customDate = sdf.parse("2000-02-29");
} catch(Exception e) {

}
System.out.println(customDate);这样倒是可以生成指定的日期了。可是，怎么提取出年月日时分秒等
怎么加减年月日时分秒等呢？

Calendar类对时间操作挺全的,查一下!!

private static  char   DAY_DELIMITER  = '-';
  public  static  int    YEAR           = Calendar.YEAR;
  public  static  int    MONTH          = Calendar.MONDAY;
  public  static  int    DAY            = Calendar.DAY_OF_MONTH;
  public  static  int    HOUR           = Calendar.HOUR_OF_DAY;
  public  static  int    MINUTE         = Calendar.MINUTE;
  public  static  int    SECOND         = Calendar.SECOND;  Calendar calendar = new GregorianCalendar(Integer.parseInt(datetime.substring(0,4)),
                                            Integer.parseInt(datetime.substring(5,7))-1,
                                            Integer.parseInt(datetime.substring(8,10)),
                                            Integer.parseInt(datetime.substring(11,13)),
                                            Integer.parseInt(datetime.substring(14,16)),
                                            Integer.parseInt(datetime.substring(17,19))
                                            );private  static String getDateTime(Calendar calendar)
  {
    StringBuffer buf = new StringBuffer("");    buf.append(calendar.get(calendar.YEAR));
    buf.append(DAY_DELIMITER);
    buf.append(calendar.get(calendar.MONTH)+1>9?calendar.get(calendar.MONTH)+1+"":"0"+(calendar.get(calendar.MONTH)+1));
    buf.append(DAY_DELIMITER);
    buf.append(calendar.get(calendar.DAY_OF_MONTH)>9?calendar.get(calendar.DAY_OF_MONTH)+"":"0"+calendar.get(calendar.DAY_OF_MONTH));
    buf.append(" ");
    buf.append(calendar.get(calendar.HOUR_OF_DAY)>9?calendar.get(calendar.HOUR_OF_DAY)+"":"0"+calendar.get(calendar.HOUR_OF_DAY));
    buf.append(":");
    buf.append(calendar.get(calendar.MINUTE)>9?calendar.get(calendar.MINUTE)+"":"0"+calendar.get(calendar.MINUTE));
    buf.append(":");
    buf.append(calendar.get(calendar.SECOND)>9?calendar.get(calendar.SECOND)+"":"0"+calendar.get(calendar.SECOND));
    return buf.toString();
  }@return YYYY-MM-DD HH:MM:DD

Answer 4

用Calendar这个类，sun不推荐用Date这个类生成日期

Answer 5

java.util.Calendar calendar = java.util.Calendar.getInstance();
calendar.set(2000, 1, 29);
System.out.println(calendar.getTime());
输出即为：Tue Feb 29 11:10:09 CST 2000。
需要注意：Month value is 0-based. e.g., 0 for January.
