Given:

a JAR containing a MIDlet named TesterMIDlet

a JAD with this content: CertificationExam:

Sun Certified Mobile Application DeveloperMIDlet-1: TesterMIDlet, , certification.TesterMIDlet MIDlet-Jar-Size: 2038 MIDlet-Jar-URL: Certification.jar MIDlet- Name: Certification MIDlet-Vendor: A Testing Company MIDlet-Version: 1.0

MicroEdition- Configuration: CLDC-1.0 MicroEdition-Profile: MIDP-2.0

This MIDlet needs to get the property with the key CertificationExam defined in the JAD. This needs to be assigned to a String ExamName from within the MIDlet.startApp() method.

What is the correct way to accomplish this?

A. String ExamName = this.getAppProperty("CertificationExam");

B. String ExamName = this.getAppProperty("MIDlet-CertificationExam");

C. String ExamName = System.getProperty("CertificationExam");

D. String ExamName = System.getProperty("MIDlet-CertificationExam");

A. In class A, no new events will be delivered to the application until after the commandAction() method completes.

B. The event-handling mechanism in class A allows multiple command events to be delivered to the application in parallel.

C. The commandAction() method code in class B is compliant with the event-handling approach recommended in the MIDP 2.0 specification.

D. The commandAction() method code in class A is NOT guaranteed to be portable across all MIDP 2.0-compliant devices.

E. In class B, no new events will be delivered to the application until after the commandAction() method completes.

F. The event-handling in class A will NOT print done with action until after the run() method has completed.

Given the MIDlet code:

20.

String arg = "telepathy:op=mind.read, target=James.Gosling";

Given two options to synthesize tones: Manager.playTone(); And:

5. //...

11.

Player p = Manager.createPlayer(Manager.TONE_DEVICE_LOCATOR);

12.

p.realize();

13.

ToneControl c = (ToneControl)p.getControl("ToneControl");

14.

c.setSequence(sequence);

15.

p.start();

Which is true?

A. Manager.TONE_DEVICE_LOCATOR is not a valid field.

B. The second option lets developers set playback tempo.

C. Both options have the same result.

D. The second option lets developers set playback pitch.

What are two benefits of the PushRegistry? (Choose two.)

A. It provides a way for the AMS to automatically invoke a MIDlet at a specified time if it is not already running.

B. It provides a way for an incoming connection to invoke a MIDlet that can handle the content sent by the connection.

C. It provides a way for two MIDlet suites running on the same device to discover and communicate with each other in a secure manner.

D. It provides a way to restrict HTTP connections to well-known network addresses.
