Properties vs Resource Bundle

I read about properties and resource bundle. But I was unable to get difference between these. When to use Properties file and when to use Resource bundle.

To load properties file use the following code

Properties tempProp = new Properties();
FileInputStream propsFile = new FileInputStream(xyz.properties);
tempProp.load(propsFile);

To load Resource bundle

ResourceBundle labels =
    ResourceBundle.getBundle("xyz", currentLocale);
Enumeration bundleKeys = labels.getKeys();

In both of the cases (in resource bundle and in Properites) we are using properties file. The one difference I found is that to store application specific data we use properties file and to use i18n data we use resource bundle. I don't know whether i am right or not.

I would like to know the use of the above two. What is the difference between these two.

  1. Properties usually used for configuration file, not designed for internationalization (i18n) file. Such as log4j.properties or as your own configuration file.
  2. ResourceBundle is used for internationlization (i18n), the "magic" of ResourceBundle is not only key-value pair, but it can set to spesific Locale (language,region/country,variant) with the same key.

So, yes. it depends on what you need.

Resource Bundle: always considers your property files as part of the classpath. If you deploy the project, the property file actually goes into the actual deployment.

The Property Class loads the property files but the property files should not necessarily be in the classpath, or should not the part of the deployment file. it might be somewhere in the operating system or in some folder.
