util的date
public class Date1 {
public static void main(String[] args) throws ParseException {
Date date=new Date();
String localeString = date.toLocaleString();
System.out.println(localeString);
System.out.println(date.getTime());
SimpleDateFormat sdf=new SimpleDateFormat("yyyy;MM;dd;;hh;mm;ss");
String ss=sdf.format(date);
Date date2=new Date(1498481243639l);
System.out.println(date2);
}
}
public static void main(String[] args) throws ParseException {
Date date=new Date();
System.out.println(date.toLocaleString());
long time = date.getTime();
System.out.println(time);
Date date2 = new Date(1498464859777l);
System.out.println(date2);
String dString="2015-12-12 20:53:12";
SimpleDateFormat simpleDateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
String dd="2017-06-25 16:20:26";
Date date2 = simpleDateFormat.parse(dd);
System.out.println(date2);
}
數據庫中的date
util 轉 sql
String datea = t_news.getDatea();
SimpleDateFormat simpleDateFormat = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss");
Date parse = simpleDateFormat.parse(datea);
Timestamp timestamp = new Timestamp(parse.getTime());
pst.setTimestamp(4,timestamp);
util 轉 sql 日期
Date date = new Date();
Timestamp timestamp = new Timestamp(date.getTime());
util 轉 sql 日期
String birthday = person.getBirthday();
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
java.util.Date date = sdf.parse(birthday);
Date bt=new Date(date.getTime());
sql 轉 util 日期
Timestamp timestamp = rs.getTimestamp(5);
String localeString = timestamp.toLocaleString();
sql 轉 util 日期
Date date = rs.getDate(3);
SimpleDateFormat simpleDateFormat =new SimpleDateFormat("yyyy-MM-dd");
String birthday = simpleDateFormat.format(date);
