How to Convert 'dd/MM/yyyy' to 'yyyy/MM/dd' Date Format in Java?

Alter Date Representation in Java

Transforming date formats is a common need in Java applications. One such requirement is converting from "dd/MM/yyyy" to "yyyy/MM/dd" format.

To achieve this, leverage the SimpleDateFormat class:

final String OLD_FORMAT = "dd/MM/yyyy";
final String NEW_FORMAT = "yyyy/MM/dd";

// Source date: August 12, 2010
String oldDateString = "12/08/2010";
String newDateString;

SimpleDateFormat sdf = new SimpleDateFormat(OLD_FORMAT);
Date d = sdf.parse(oldDateString);
sdf.applyPattern(NEW_FORMAT);
newDateString = sdf.format(d);

This code creates a new SimpleDateFormat object with the initial format ("dd/MM/yyyy") and parses the specified date into a Date object. The pattern is then modified to the desired format ("yyyy/MM/dd") before formatting the Date object to obtain the new date string.
