Question

I’ve multiple messages file (messages_en.properties, messages_ch.properties)

These files are having some static html text & need some dynamic input param such as username so that it’ll say Dear {0}, thanks for subscription....

Now i need to substitute username there after reading those contents from appropriate file.

How can I do that in Java? Is there any framework sample code available?

Answer 1

See the I18N trail. Nutshell version from that tutorial, using newer API methods:

    ResourceBundle messages = ResourceBundle.getBundle("MessageBundle", Locale.getDefault());
    String output = MessageFormat.format(messages.getString("msg.key"), "Mike");

Depending on your actual usecase there may be some shortcuts (e.g., web frameworks often include direct support for localization via tag libraries, some libraries wrap up some busywork, etc.)
