Question

Is there a way to pass an array of String to a resource bundle to localize an unknown number of argument for a given key?

I have:

my.message=List of retired products: {0}

getValue(bundle, "my.message", list.toArray());

With this, only the first item in the array is showed in the resulting message.

No, there are no builtin facilities for that in the MessageFormat API. You need to build a string with the values yourself. E.g.:

StringBuilder products = new StringBuilder();
for (int i = 0; i < list.size(); i++) {
    products.append(list.get(i));
    if (i + 2 < list.size()) products.append(", ");
    else if (i + 2 == list.size()) products.append(" and "); // Localize this?
}
getValue(bundle, "my.message", products);
