How to Set the Default Locale in the JVM?

Setting the Default Locale in the JVM

Introduction:
The Java Virtual Machine (JVM) provides mechanisms for setting the default locale, which governs the language, region, and cultural conventions used in applications. Here are some methods to specify the default locale in the JVM.

1. Command Line JVM Parameters:
You can set the default locale on the command line when launching the JVM using the following JVM parameters:

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

This sets the default country code to CA and the default language code to fr.

2. Java Code:
You can also set the default locale programmatically using the Locale.setDefault() method:

Locale.setDefault(new Locale("fr", "CA"));
