Java Localization
Internationalization is the process of creating a software application that can be translated into different languages and regions without modifying the application. Creating a locale-specific application raises the cost of the application and necessitates extensive maintenance.
Localization is the process of adapting internationalized software for a specific region or country by translating text and adding locale-specific components.
As a result, it is beneficial to create an application based on the concept of internationalization. It saves time, reduces development costs, and requires less effort to maintain.
Before delving into the term "Localization," it is critical to comprehend the concept of "Internationalization."
Internationalization:
The process of creating an application that supports several languages, number formats, currencies, dates, times, and other formats is known as internationalization. It is an essential component of any modern multilingual system. For worldwide production, there is a highly popular shorthand (maybe even more popular than the full name) - "I18N" because of the 18 characters between I and 'n'.
Modern business systems must service people from many regions/countries around the world, as well as from various cultural backgrounds. Different cultural or linguistic regions determine not just the specific meanings of a language, but also the type of currency, numerical representation, and even date and time variations.
Look at the following representation.
514,220.13 (United States)
503 220,12 (Poland)
227,12 (Germany)
Similarly, the date and time formats are also different. For example:
- Thursday, March 3, 2022, 16:30:14 PM CET (United States)
- lundi 1 mardi 2022 16 h 30 CET (France)
- 2022?1?1? ??? ??16?30?14? CET (China)
What's more, we know that there are unique currency symbols for different countries:
- £5,4000.80 (United Kingdom)
- €400,80 (Italy)
- 7 400,80 € (France)
- $7,400.80 (United States)
Localization:
We have a nice feature in Java called the Locale class at our disposal. It enables us to swiftly distinguish between cultural locales and organise our material accordingly. Localization, like I18N, has its own acronym: "I10N" because to the 10 letters between "I" and "N." The key rationale for utilising Locale is that it allows access to all essential local-specific formatting without requiring recompilation. Because the application can handle many locales at once, adding a new language is simple.
Localization is also the process of tailoring a product's content to a given location or language. Word translation is a well-known aspect of this process, but it is not the only one. Locale practises frequently include:
- Numbers
- Dates
- Currencies
- Images and sounds
- Layouts
Benefits of localization :
The same executable can execute globally with the addition of localized data.
The system has no solid codes for text components such as status messages and GUI component labels. They are instead saved without source code and retrieved dynamically.
It is not necessary to re-integrate support for new languages.
Custom-based data, such as dates and currency types, show in formats appropriate to the end user's locale and language.
Locale.Builder:
Locale.Builder is another possibility. Locale.Builder contains five set methods that we can utilize to generate an object while also validating its values:
Locale locale = new Locale.Builder( )
Locale locale = new Locale.Builder( )
.setLanguage( " fr " )
.setRegion( " CA " )
.setVariant( " POSIX " )
.setScript( " Latn " )
.build( ) ;
The String representation of the above Locale is fr_CA_POSIX_#Latn.
It is important to understand that the 'variant' set can be challenging since there are no legal constraints to various values, despite the fact that the set technique requires compliance with BCP-47. Otherwise, it will issue an IllformedLocaleException.
Locale constructors can be used in situations when we need to utilize a value that does not exceed the guarantee since they do not validate values.
Importance of Locale Class :
A Locale class object describes a geographical or cultural region. This object can be used to obtain location-specific information such as the country name, language, variation, and so on.
