Question

如何将DateTime类型转换成String类型

Answer 1

Date转换为Datetime

Datetime在java数据库中对应的是Timestamp，转换如下：

[java] view
plaincopyprint?

//java.util.Date转换为Timestamp

Date date = new Date();

Timestamp timestamp = new Timestamp(date.getTime()); //2013-01-14 22:45:36.484
//java.util.Date转换为Timestamp
Date date = new Date();
Timestamp timestamp = new Timestamp(date.getTime()); //2013-01-14 22:45:36.484

(2) String转换为Date

[java] view
plaincopyprint?

//String转换为java.util.Date

String str = "2013-01-14";

SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");

Date date = null; //初始化date

try {

date = sdf.parse(str); //Mon Jan 14 00:00:00 CST 2013

} catch (ParseException e) {

e.printStackTrace();

}
