Are there any guarantees in JLS about order of execution static initialization blocks?
- by Roman
I wonder if it's reliable to use a construction like:
private static final Map<String, String> engMessages;
private static final Map<String, String> rusMessages;
static {
engMessages = new HashMap<String, String> () {{
put ("msgname", "value");
}};
rusMessages = new HashMap<String, String> () {{
put ("msgname", "????????");
}};
}
private static Map<String, String> msgSource;
static {
msgSource = engMessages;
}
public static String msg (String msgName) {
return msgSource.get (msgName);
}
Is there a possibility that I'll get NullPointerException because msgSource initialization block will be executed before the block which initializes engMessages?
(about why don't I do msgSource initialization at the end of upper init. block: just the matter of taste; I'll do so if the described construction is unreliable)
