J2ME MCQs

Java ME is a family of specifications for developing mobile applications. It defines configurations like CLDC and CDC that provide core class libraries, and profiles like MIDP that build on configurations to provide additional APIs for user interfaces, networking, and other domains. A Java ME device can support multiple profiles to provide different functionality.

2. What is a configuration? A. configuration defines a set of class libraries available for a particular domain of devices. B. A configuration defines a vertical (or specialized) set of classes. C. A configuration defines a minimum set of class libraries for a wide range of devices. D. All of the above.
3. What is a profile? A. A profile defines a set of class libraries available for a wide range of devices. B. A profile defines a horizontal set of classes that a configuration can use. C. A profile defines the set of APIs available for a particular family of devices. D. A profile is the foundation for a configuration
4. The Personal Digital Assistant (PDA) Profile is based on: A. A. Connected Device Configuration (CDC). B. Connected Limited Device Configuration (CLDC).
5. The Foundation profile A. A. Extends the CDC by adding the missing user interface APIs. B. Extends the CLDC by adding the missing Java 2, Standard Edition (J2SE) core libraries. C. Is meant to serve as a foundation for other profiles. D. All of the above.
6. The RMI profile is meant to be used with: A. CLDC and MIDP B. CDC and Foundation C. Both A and B
