Setting Default Locale in Java Virtual Machine (JVM)

To establish a customized default locale for your JVM, multiple approaches are available. The most commonly known method is through the Locale.setDefault() API. However, there is an alternative option that can be employed:

Command-Line Parameters

You can directly specify the default locale by adding JVM parameters during command-line execution. For instance, to set the default locale to French Canadian (fr_CA), you would specify the following parameters:

java -Duser.country=CA -Duser.language=fr ... com.x.Main

Explanation:

• -Duser.country=CA: Sets the default country code to Canada.
• -Duser.language=fr: Sets the default language code to French.
