conn.send(message);
What exception will this code throw if a timeout occurs while trying to send the message?

• A.java.io.EOFException
• B.java.lang.SecurityException
• C.java.io.InterruptedIOException
• D.java.lang.NullPointerException

Which three APIs may untrusted MIDlets use without explicit confirmation by the user?
(Choose three.)

• A.javax.microedition.io.PushRegistry
• B.javax.microedition.io.HttpConnection
• C.javax.microedition.lcdui
• D.javax.microedition.rms
• E.javax.microedition.media

Which two clarifications does the JTWI specification make regarding how devices implement the Mobile Media API? (Choose two.)

• A.A JTWI device must support HTTP for media file download of all supported media formats.
• B.A JTWI device must support Real Time Streaming Protocol (RTSP) for media file download of all supported media formats.
• C.A JTWI device must support MIDI file playback.
• D.A JTWI device must support WAV file playback.
• E.A JTWI device must support MP3 file playback.

Click the Exhibit button.
The method in the Exhibit must create an HTTP GET connection that works reading both of the following HTTP server response cases:
HTTP server response headers n.1
1 . HTTP/1.1 200 OK
2 . Server: MyServer/1.3.0
3 . Content-Length: 3245
4 . Content-Type: text/html
HTTP server response headers n.2
1 . HTTP/1.1 200 OK
2 . Server: MyServer/1.3.0
3 . Content-Type: text/html
Which two can be used in the fragment of code starting at line 12? (Choose two.)

• A.12. if (len > 0) {
  1 3. byte[] data = new byte[len];
  1 4. int actual = is.read(data);
  1 5. //...
  2 0. } else {
  2 1. int ch;
  2 2. while ((ch = is.read()) != -1) {
  2 3. //...
  3 0. }
  3 1. }
• B.12. int ch;
  1 3. while ((ch = is.read()) == -1) {
  1 4. //...
  2 0. }
• C.12. int ch;
  1 3. while ((ch = is.read()) != -1) {
  1 4. //...
  2 0. }
• D.12. byte[] data = new byte[len];
  1 3. int actual = is.read(data);

Given:
1 . import javax.microedition.midlet.*;
2 . public class Foo extends MIDlet {
3 . public void go() {
4 . try {
5 . doStuff();
6 . } catch(java.lang.NoClassDefFoundError e) { }
7 . }
8 . void doStuff() { }
9 . public void destroyApp(boolean b) { }
1 0. public void pauseApp() { }
1 1. public void startApp() {go();}
1 2. }
Assuming the application is targeted for CLDC 1.1, what is the result?

• A.Compilation succeeds.
• B.Compilation fails because of a problem in line 8.
• C.Compilation fails because of a problem in line 6.
• D.Compilation fails because the class does not contain the required method implementations.
