javax.microedition.io.PushRegistry javax.microedition.io.Connector.socket
javax.microedition.io.Connector.serversocket
Which is true?
A. When an incoming socket connection activates the MIDlet, the MIDlet may be unable to retrieve that connection while starting up.
B. When an incoming socket connection activates the MIDlet, the MIDlet can always retrieve that connection while starting up.
C. When an incoming socket connection activates the MIDlet, the MIDlet will always be unable to retrieve that connection while starting up.
D. The MIDlet CANNOT receive incoming socket push notifications without the permission javax.microedition.io.Connector.socketreceiver.
Given:
MIDlet-Push-1: datagram://:444, com.fooworks.PushExample, *

14.
connections = PushRegistry.listConnections(false);
15.
for (int i=0; i < connections.length; i++) {
16.
new DatagramHandler(connections[i]).start();
17.
}
18.
} else {
19.
for (int i=0; i < connections.length; i++) {
20.
new DatagramHandler(connections[i]).start();
21.
}
22.
}
23.
}
Which two identify what will go wrong if the code is invoked by the Application Management Software in response to an inbound connection notification? (Choose two.)
A. An IOException is thrown if there are no active connections.
B. Datagrams for the active connection are handled, but any datagrams sent to the other port are missed.
C. The first inbound datagram is ignored, all subsequent datagrams are handled by DatagramHandler.
D. The first inbound datagram is handled, but all other datagrams are missed.
E. Duplicate DatagramHandler objects are created if the MIDlet is paused and then resumed.
Given:

C. Device substitutes its closest substitute.
D. Compile time error occurs.
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. SecurityException is thrown at runtime.
B. Property is set to "CLDC-1.1."
C. Compilation fails because of an error in line 11.
D. Compilation fails because of an error in line 7.
Given the JAD file fragment:
MIDlet-1: Calendar, calendar.png, com.example.CalendarMIDlet
MIDlet-2: Chat, chat.png, com.example.ChatMIDlet
What CalendarMIDlet code launches ChatMIDlet at the time specified by variable chatTime?
A. PushRegistry.registerAlarm("MIDlet-1", chatTime);
B. PushRegistry.registerAlarm ("com.example.ChatMIDlet", chatTime);
C. PushRegistry.registerAlarm("Chat", chatTime);
D. PushRegistry.registerAlarm (Class.forName("com.example.ChatMIDlet"), chatTime);
A MIDlet has registered a push connection in the PushRegistry and a connection notification is pushed to the device. Which two are true? (Choose two.)
A. If the MIDlet is NOT running, the Application Management Software starts the MIDlet.
B. If the application is running, it is responsible for all I/O operations associated with the inbound connection.
C. The Application Management Software is always responsible for any inbound notification requests.
D. Once a connection is registered in the PushRegistry, the Application Management Software is always responsible for any connections.
E. If the MIDlet is in the paused state, the Application Management Software is responsible for any inbound notification requests.
