The IDE lets you easily deal with an object's properties by storing them in resource bundles. Each resource bundle consists of a group of properties (.properties) files. You can manage a resource bundle's contents through its Explorer nodes, as a text file in the Source Editor, or using a special properties pane in the Source Editor.
The IDE also automates the process of internationalizing your source code. You can use the internationalization features to automatically replace hard-coded strings with internationalized ones, insert new internationalized strings as you write code, and check your resource bundles to ensure they contain all of the necessary keys.
