Changing the date format to mm-dd-yyyy hh:mm
提问by Little bird
I'm trying to use this code:
我正在尝试使用此代码：
private static Date getTimeStamp() {
return new Timestamp(new Date().getTime());
}
What I'm getting is 2013-03-13 12:46:22.011
我得到的是 2013-03-13 12:46:22.011
But what I need is that the timestamp should be in the format of mm-dd-yyyy hh:mm.
但我需要的是时间戳的格式应该是mm-dd-yyyy hh:mm.

java.sql.Timestampobjects (just like java.util.Dateand java.sql.Date) do not have a format by themselves, so you cannot "have a Timestamp in the format [whatever]".
java.sql.Timestamp对象（就像java.util.Dateand java.sql.Date）本身没有格式，所以你不能“有格式[任何]的时间戳”。
A format only is applicable when you convert the object to a string for display. You can use SimpleDateFormatto convert a Timestampto a string, using the format you want.
仅当您将对象转换为字符串进行显示时，格式才适用。您可以使用所需的格式SimpleDateFormat将 a 转换Timestamp为字符串。
Timestamp timestamp = new Timestamp(System.currentTimeMillis());
DateFormat dateFormat = new SimpleDateFormat("MM-dd-yyyy HH:mm");
String text = dateFormat.format(timestamp);
System.out.println(text);

希望这可以帮助
String date1="2013-03-13 12:46:22.011";
DateFormat userDateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:SS");
DateFormat dateFormatNeeded = new SimpleDateFormat("MM/dd/yyyy HH:mm");
Date date = userDateFormat.parse(date1);
String finaldate = dateFormatNeeded.format(date);

You can use SimpleDateFormat http://docs.oracle.com/javase/6/docs/api/java/text/SimpleDateFormat.htmlto achieve your goal.
您可以使用 SimpleDateFormat http://docs.oracle.com/javase/6/docs/api/java/text/SimpleDateFormat.html来实现您的目标。
For Example: new SimpleDateFormat("MM-dd-yyyy HH:mm").format(timestamp));
例如： new SimpleDateFormat("MM-dd-yyyy HH:mm").format(timestamp));
