Question 11 :
What is optional package
An optional package is a set of J2ME APIs providing services in a specific area, such as database access or multimedia. Unlike a profile, it does not define a complete application environment, but rather is used in conjunction with a configuration or a profile.

J2ME RMI and the Mobile Media RMI are examples of optional packages.
