載入屬性

要載入與應用程式繫結在一起的屬性檔案：

public class Defaults {

    public static Properties loadDefaults() {
        try (InputStream bundledResource =
            Defaults.class.getResourceAsStream("defaults.properties")) {

            Properties defaults = new Properties();
            defaults.load(bundledResource);
            return defaults;
        } catch (IOException e) {
            // Since the resource is bundled with the application,
            // we should never get here.
            throw new UncheckedIOException(
                "defaults.properties not properly packaged"
                + " with application", e);
        }
    }

}
