如何在jframe标题栏上显示当前日期？

Question

I searched for the solution but couldn't find one. I want to show the current date on my jframe title bar. I know how to get current date using java but I need to show it on the title bar. Can anyone help me regarding this ?

Thanks in advance.

Answer 1

To get current date> use java.util.Date

To format the date> use java.text.SimpleDateFormat

To set title for JFRame>

JFrame jFrame= new JFrame("title");

or

jFrame.setTitle("title");

So the solution is,

DateFormat dateFormat = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss");
Date date = new Date();

JFrame jFrame= new JFrame("Current Date: "+dateFormat.format(date));

or 

jFrame.setTitle("Current Date"+dateFormat.format(date));

The answer by Nidheesh is correct.

Localizing With Joda-Time

If you want a localized format for the date, use the Joda-Time library.

DateTime now = DateTime.now( DateTimeZone.getDefault() );

Or, if you have a java.util.Date to convert to Joda-Time.

DateTime dateTime = new DateTime( date, DateTimeZone.forID( "America/Montreal" ) );

Generate a string representation of the date-time value using a localized format. Use a Locale object with the Joda-Time DateTimeFormat.forStyle .

java.util.Locale locale = new Locale( "fr", "CA" ); // Québécois style.
DateTimeFormatter formatter = DateTimeFormat.forStyle( "SS" ).withLocale( locale );
String output = formatter.print( now );
