  C. The RMS record stores of the updated MIDlet suite are always lost.
  D. A MIDlet suite CANNOT be updated with another MIDlet suite that has a lower value for the MIDlet-Version attribute.
  A. An unsigned MIDlet suite must NOT be allowed to update a signed MIDlet suite.

• Question 332:

  A. If the installation status report CANNOT be sent, the device must refuse the installation of the MIDlet suite.
  B. In response to an installation status report, the server must reply with a 200 OK. HTTP acknowledgement response.

• Question 334:

  The developer is designing a game that uses the LayerManager and Sprite classes. Three Sprite objects are added to a LayerManager object and a call is placed to the LayerManager.paint(Graphics, x, y) method. In what order are the Sprite objects rendered to the device display?

  A. The Sprites are rendered in an implementation specific manner.
  B. The Sprites are rendered in a random order.
  C. The Sprites are rendered in order of descending index.
  D. The Sprites that are animated are rendered first.
  C. The Sprites are rendered in order of descending index.

• Question 335:

  Given:

  50.

  class MyGameCanvas extends Canvas {

  51.

  //...

  60.

  public MyGameCanvas() {

  61.

  int width1 = getWidth();

  62.

  int height1 = getHeight();

  63.

  //...

  70.

  setFullScreenMode(true);

  71.

  //...

  80.

  int width2 = getWidth();

  81.

  int height2 = getHeight();

  82.

  //...

  90. }

  What is true about width1, height1 and width2, height2?

  A. The call to setFullScreenMode() is ignored because the dimensions have already been set.
  B. The system tries to provide maximum visible area to the MIDlet and these dimensions are width2, height2.
  C. height1 is always equal to height2.
  D. width1 is always equal to width2.
  B. The system tries to provide maximum visible area to the MIDlet and these dimensions are width2, height2.

• Question 336:

  Given the MIDlet code:

  7.

  String s = System.getProperty("microedition.configuration");

  8.

  if (!s.equals("CLDC-1.1")) {

  9.

  s = "CLDC-1.1";

  10.

  }

  11.

  System.setProperty(s); Which statement is true?

  A. Compilation fails because of an error in line 7.
  B. Property is set to "CLDC-1.1."
  C. SecurityException is thrown at runtime.
  D. Compilation fails because of an error in line 11.
  D. Compilation fails because of an error in line 11.

• Question 337:

  Given a MIDP 2.0 device supports alpha blending, a MIDlet needs to render semi- transparent images of size 10x10 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 10x10, 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
  D. use createRGBImage() to create an immutable Image from ARGB data with the desired values

• Question 338:

  Given the MIDlet code:

  7.//..

  10.public void startApp(){

  11.Float f = new Float(3.14);

  12.System.out.println("Pi: " + f);

  13.

  14.}

  15.//..

  What is the result when working with a CLDC 1.1 implementation?

  A. Compilation fails.
  B. An exception is thrown at runtime.
  C. Pi: 3.14 is sent to the system console.
  D. Pi: 3.14 is sent to the device display.
  C. Pi: 3.14 is sent to the system console.

• Question 339:

  Which three are basic interface types addressed by the Generic Connection Framework? (Choose three.)

  A. telephony-oriented mechanism
  B. circuit-oriented mechanism
  C. location-oriented mechanism
  D. basic serial output connection
  E. basic serial input connection
  B. circuit-oriented mechanism
  D. basic serial output connection
  E. basic serial input connection

• Question 340:

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