display Java.util.Date in a specific format
JavaDateJava Problem Overview
I have the following scenario :
SimpleDateFormat dateFormat = new SimpleDateFormat("dd/MM/yyyy");
System.out.println(dateFormat.parse("31/05/2011"));
gives an output
Tue May 31 00:00:00 SGT 2011
but I want the output to be
31/05/2011
I need to use parse here because the dates need to be sorted as Dates and not as String.
Any ideas ??
Java Solutions
Solution 1 - Java
How about:
SimpleDateFormat dateFormat = new SimpleDateFormat("dd/MM/yyyy");
System.out.println(dateFormat.format(dateFormat.parse("31/05/2011")));
> 31/05/2011
Solution 2 - Java
You need to go through SimpleDateFormat.format
in order to format the date as a string.
Here's an example that goes from String
-> Date
-> String
.
SimpleDateFormat dateFormat = new SimpleDateFormat("dd/MM/yyyy");
Date date = dateFormat.parse("31/05/2011");
System.out.println(dateFormat.format(date)); // prints 31/05/2011
// ^^^^^^
Solution 3 - Java
Use the SimpleDateFormat.format
SimpleDateFormat sdf = new SimpleDateFormat("dd/MM/yyyy");
Date date = new Date();
String sDate= sdf.format(date);
Solution 4 - Java
You can use simple date format in Java using the code below
SimpleDateFormat simpledatafo = new SimpleDateFormat("dd/MM/yyyy");
Date newDate = new Date();
String expectedDate= simpledatafo.format(newDate);
Solution 5 - Java
It makes no sense, but:
System.out.println(dateFormat.format(dateFormat.parse("31/05/2011")))
SimpleDateFormat.parse() = // parse Date from String
SimpleDateFormat.format() = // format Date into String
Solution 6 - Java
If you want to simply output a date, just use the following:
System.out.printf("Date: %1$te/%1$tm/%1$tY at %1$tH:%1$tM:%1$tS%n", new Date());
As seen here. Or if you want to get the value into a String (for SQL building, for example) you can use:
String formattedDate = String.format("%1$te/%1$tm/%1$tY", new Date());
You can also customize your output by following the Java API on Date/Time conversions.
Solution 7 - Java
java.time
Here’s the modern answer.
DateTimeFormatter sourceFormatter = DateTimeFormatter.ofPattern("dd/MM/uuuu");
DateTimeFormatter displayFormatter = DateTimeFormatter
.ofLocalizedDate(FormatStyle.SHORT)
.withLocale(Locale.forLanguageTag("zh-SG"));
String dateString = "31/05/2011";
LocalDate date = LocalDate.parse(dateString, sourceFormatter);
System.out.println(date.format(displayFormatter));
Output from this snippet is:
> 31/05/11
See if you can live with the 2-digit year. Or use FormatStyle.MEDIUM
to obtain 2011年5月31日
. I recommend you use Java’s built-in date and time formats when you can. It’s easier and lends itself very well to internationalization.
If you need the exact format you gave, just use the source formatter as display formatter too:
System.out.println(date.format(sourceFormatter));
> 31/05/2011
I recommend you don’t use SimpleDateFormat
. It’s notoriously troublesome and long outdated. Instead I use java.time, the modern Java date and time API.
To obtain a specific format you need to format the parsed date back into a string. Netiher an old-fashioned Date
nor a modern LocalDate
can have a format in it.

Solution 8 - Java
You already has this (that's what you entered) parse
will parse a date into a giving format and print the full date object (toString
).
Solution 9 - Java
This will help you. DateFormat df = new SimpleDateFormat("dd/MM/yyyy"); print (df.format(new Date());
Solution 10 - Java
I had something like this, my suggestion would be to use java for things like this, don't put in boilerplate code
Solution 11 - Java
This looks more compact. Finishes in a single line.
import org.apache.commons.lang3.time.DateFormatUtils;
System.out.println(DateFormatUtils.format(newDate, "yyyy-MM-dd HH:mm:ss"));
