Ans: ResourceManager class is used to get a single instance of the IResourceManager implementation. The IResourceManager and IResourceBundle interfaces work together to provide internalization support for flex application.
When any component that extend UIComponent, validator or formatter now have a new resource property, which easily access the single instance of this manager.
getInstance() method gets the single instance of the ResourceManager class. This object manages all localized resources for a Flex application.
