There are three constructors available for the creation of Locale objects. There are four ways to create Locale objects. Some of the Local-sensitive classes defined in the Java Standard API are:
400 for Germany 302, 400 for the United States.
Thus, NumberFormat may return a number as 302 400 for France 302. These classes use the Locale object to understand which locale is being used in the application a good example would be the NumberFormat class. Objects that you create from locale-sensitive classes customize themselves as to how to format and present data to the user. Real localization is done by locale-sensitive classes. To define the locale for the application(language, country, and variant), you would use the Locale object, which is only an identifier.
The concept of Java locale is implemented by the class. Using the Locale.forLanguageTag Factory Method.
