How to implement internationalization in java

Question

I have a class called `Info`, and i have a bunch of `static String` variables described in it. ``` public class Info{ public static stringOne= "Hello"; public static stringTwo = "world"; } ``` and i'm hoping to access these variables as `Info.stringTwo` from other classes. 1.) I need to know if this is `java-Internationalization` that i have applied here ? (I have all the messages that i will display in the application assigned in this class. And, i am hoping to have different languages support to the app as well)

Accepted Answer

Have a look at Resource bundle

A copy paste from the documentation:

When your program needs a locale-specific object, it loads the ResourceBundle class using the getBundle method:

```
 ResourceBundle myResources =
 ResourceBundle.getBundle("MyResources", currentLocale);
```

Resource bundles contain key/value pairs. The keys uniquely identify a locale-specific object in the bundle.

Here's an example of a ListResourceBundle that contains two key/value pairs:

```
 public class MyResources extends ListResourceBundle {
     protected Object[][] getContents() {
         return new Object[][] {
             // LOCALIZE THE SECOND STRING OF EACH ARRAY (e.g., "OK")
             {"OkKey", "OK"},
             {"CancelKey", "Cancel"},
             // END OF MATERIAL TO LOCALIZE
        };
     }
 }
```

Keys are always Strings. In this example, the keys are "OkKey" and "CancelKey". In the above example, the values are also Strings--"OK" and "Cancel"--but they don't have to be. The values can be any type of object. You retrieve an object from resource bundle using the appropriate getter method. Because "OkKey" and "CancelKey" are both strings, you would use getString to retrieve them:

```
button1 = new Button(myResources.getString("OkKey"));
button2 = new Button(myResources.getString("CancelKey"));
```
