Internationalization and Localization
Create an application to explore the available locales included in the standard Java Development Kit.

The main specifications of the application are:

Compulsory (1p)

Create a package with the name res. Inside this package create the files: Messages.properties, Messages_ro.properties.

#Messages.properties file
prompt = Input command:
locales = The available locales are:
locale.set = The current locale is {0}
info = Information about {0}:
invalid = Unknown command

#Messages_ro.properties file
prompt = Comanda ta:
locales = Localizarile disponibile sunt:
locale.set = Localizarea curenta este {0}
info = Informatii despre localizarea {0}:
invalid = Comanda necunoascuta

Create the package com and implement the following classes describing commands:
- DisplayLocales: to display all available locales
- SetLocale: to set the application current locale.
- Info: to display information about the current or a specific locale.
  When the user sets a specific language tag, various information obtained using standard Java classes such as Currency or DateFormatSymbols should be displayed in a text area, as in the following example:
  - Country: Romania (România)
  - Language: Romanian (română)
  - Currency: RON (Romanian Leu)
  - Week Days: luni, marţi, miercuri, joi, vineri, sâmbătă, duminică
  - Months: ianuarie, februarie, martie, aprilie, mai, iunie, iulie, august, septembrie, octombrie, noiembrie, decembrie
  - Today: May 8, 2016 (8 mai 2016)
Create the package app and the main class LocaleExplore. Inside this class, read commands from the keyboard and execute them.
All the locale-sensitive information should be translated in at least two languages (English-default and Romanian), using the resource files.
