Example
In first ResourceBundle class we have put color name
Listing 1: EncCode_gg.java
package javabeat.net;
import java.util.ListResourceBundle;
public class EncCode_gg extends ListResourceBundle
{
public Object[][] getContents()
{
return contents;
}
Static final Object[][] contents =
{
{"color.blue", "Blue"},
{"count.green", "Green"},
{"count.white", "White"},
};
}
The another ResourceBundle contains color name in spanish language:
Listing 2: EncCode_bb.java
package javabeat.net;
import java.util.ListResourceBundle;
public class EncCode_bb extends ListResourceBundle
{
public Object[][] getContents()
{
return contents;
}
static final Object[][] contents =
{
{"color.blue", "Azul"},
{"color.green", "Verde"},
{"color.white", "Blanco"},
};
}
