What is Internationalization in Java?

Internationalization is the process of designing an application in Java that can be adapted to various local languages like Japanese, Chinese and etc to provide output in the same given language.

Problem

Let’s say, we have software that is currently used by the customers who know the English language. Later our software is going to use by non-native English users from Japan or Germany. So, in this case, these users from Japan and Germany may not feel comfortable using it.

Now, we have the following options to fix this problem:

1. To develop separate software for these new customer groups or
2. A single software that can understand customer’s locality or region and displays the language based on the that

Though, we have to use Internationalization service from Java to implement both the options, the first option is not feasible. Because the number of user locality increases the number of new software required.

The second option is the only best solution to the problem.

Hence, Java has very good support for Internationalization because it supports Unicode representation.
