Q221. – (Topic 3)
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 = System.getProperty("CertificationExam");
B. String ExamName = System.getProperty("MIDlet-CertificationExam");
C. String ExamName = this.getAppProperty("CertificationExam");
D. String ExamName = this.getAppProperty("MIDlet-CertificationExam");
Q222. – (Topic 3)
canvas.serviceRepaints(); Which two are true? (Choose two.)
A. serviceRepaints() blocks waiting for paint() to return.
B. paint() is called three times, once for each repaint() and once for serviceRepaints().
C. paint() is always called twice, once for each repaint() request.
D. If the two regions specified in repaint() overlap, repaint() may attempt to paint the union of the two areas.
Q223. – (Topic 3)
Which is false about untrusted MIDlet suites?
A. An untrusted MIDlet suite does not request permissions explicitly in the JAR manifest or the application descriptor.
B. Untrusted MIDlet suites may access protected APIs or functions if given explicit user permission.
C. JTWI devices must treat all MIDP 2.0 suites as trusted.
D. JTWI devices must treat all MIDP 1.0 suites as untrusted.

Q224. – (Topic 1)
Which is true when using multiple threads to access a record store?
A. You must coordinate access to a record store to prevent data corruption.
B. The implementation coordinates access, ensuring that record stores will NOT be corrupted.
C. You CANNOT access a record store with multiple threads.
D. You must lock a record store prior to access.

Click the Exhibit button.
The MIDlet is executed.
The MIDlet is paused and resumed two times.
What is the result?
A. c: 1
B. An exception is thrown at runtime.
C. c: 2
D. c: 3
E. c: 0
Q226. – (Topic 2)
Given a MIDP 2.0 device supports alpha blending, a MIDlet needs to render semi-transparent images of size 10×10 pixels. However, these images need to be generated at runtime. That is, they CANNOT be loaded as PNGs. What is the correct way to create a 10×10, red, semi-transparent image, using only the MIDP 2.0 API?
A. use createImage() to create a mutable Image; first fill it with white pixels, then fill it with red pixels
B. This is not possible. An Image with semi-transparency CANNOT be created at runtime.
C. use createImage() to create a mutable Image, then fill it with red pixels
D. use createRGBImage() to create an immutable Image from ARGB data with the desired values
