How Do You Format Dates in Java for Different Locales?

Locale-Sensitive Date Formatting with SimpleDateFormat

Formatting dates in Java can be tailored to different locales to meet regional preferences. The SimpleDateFormat class provides basic formatting options, but customizing these options for specific locales poses a challenge.

Challenge:

Create a Java program that formats dates in different ways based on the locale. For example, English users should see "Nov 1, 2009" ("MMM d, yyyy"), while Norwegian users should see "1. nov. 2009" ("d. MMM. yyyy").

Proposed Solution:

The initial intention was to add format strings paired with locales to SimpleDateFormat. However, this is not feasible.

Alternative Solution:

Instead of constructing your own patterns with SimpleDateFormat, use DateFormat.getDateInstance(int style, Locale locale). This method creates a DateFormatter object preconfigured for a specific style and locale.

For example, the following code creates two DateFormatter objects, one for English and one for Norwegian:

Locale englishLocale = Locale.ENGLISH;
DateFormat englishDateFormatter = DateFormat.getDateInstance(DateFormat.SHORT, englishLocale);

Locale norwegianLocale = new Locale("no", "NO");
DateFormat norwegianDateFormatter = DateFormat.getDateInstance(DateFormat.SHORT, norwegianLocale);

Using these DateFormatter objects, dates can be formatted according to the specified locales:

Date date = new Date();

String englishFormattedDate = englishDateFormatter.format(date);
String norwegianFormattedDate = norwegianDateFormatter.format(date);

This approach ensures that dates are formatted in a culturally appropriate manner based on the specified locales.
