The java.util.ListResourceBundle is a subclass of java.util.ResourceBundle.
It implements both handleGetObjects and getKeys for you.
The purpose of this bundle is to allow you to define localizable elements as a two-dimensional array of key-value pairs.
This bundle is easy to use and requires only minimal code, allowing for the focus to be on providing data in the bundle instead.
You can create your own ListResourceBundle by subclassing java.util.ListResourceBundle.
You must implement a single method, getContents(), which should return an array of key-value pairs.
The following code shows the structure of a simple bundle for the same example as above:
public class MyProgramResource extends ResourceBundle {
public Object getContents() {
return contents;
}
static Object[][] contents = {
{ "okKey", "ok" },
{ "cancelKey", "Cancel" },
}
}
The German version will look like :
public class MyProgramResource_de extends ResourceBundle {
public Object getContents() {
return contents;
}
static Object[][] contents = {
{ "okKey", "Gut"},
{"cancelKey", "Vernichten }
}
}
The UK version will look like :
public class MyProgramResource_uk extends ResourceBundle {
public Object getContents() {
return contents;
}
static Object[][] contents = {
{ "okKey", "ok" },
{ "cancelKey", "Dispose" },
}
}
ListResourceBundle can store any class of object and keys are always (quite obviously) a String object.
