In this example we shall show you how to convert dates between formats with SimpleDateFormat. To convert dates between formats with SimpleDateFormat one should perform the following steps:
- Create a new String to be used as the date that will be parsed by the SimpleDateFormat.
- Create a new SimpleDateFormat, using a String pattern to describe the date and time format.
- Invoke the
parse(String source)API method to parse the given date string and produce a Date parsed from the string. - Create a new SimpleDateFormat, using a different String pattern.
- Invoke the
format(Date date)API method to format the produced date into a new date String,
as described in the code snippet below.
package com.javacodegeeks.snippets.core;
import java.text.DateFormat;
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;
public class ConvertDatesBetweenFormatsWithSimpleDateFormat {
public static void main(String[] args) {
try {
String dateStr = "21/20/2011";
DateFormat srcDf = new SimpleDateFormat("dd/MM/yyyy");
// parse the date string into Date object
Date date = srcDf.parse(dateStr);
DateFormat destDf = new SimpleDateFormat("MM-dd-yyyy hh:mm:ss");
// format the date into another format
dateStr = destDf.format(date);
System.out.println("Converted date is : " + dateStr);
}
catch (ParseException e) {
e.printStackTrace();
}
}
}
Output:
Converted date is : 08-21-2012 12:00:00
This was an example of how to convert dates between formats with SimpleDateFormat in Java.
