Oracle Java Mobile Edition 1 Mobile Application Developer Certified Professional Sample Questions:

1. Given:
MIDlet-Push-1: datagram://:444, com.fooworks.PushExample, *
MIDlet-Push-2: datagram://:555, com.fooworks.PushExample, *
are statically registered push connections and given:
1 1. protected void startApp() {
1 2. String[] connections = PushRegistry.listConnections(true);
1 3. if(connections.length == 0) {
1 4. connections = PushRegistry.listConnections(false);
1 5. for (int i=0; i < connections.length; i++) {
1 6. new DatagramHandler(connections[i]).start();
1 7. }
1 8. } else {
1 9. for (int i=0; i < connections.length; i++) {
2 0. new DatagramHandler(connections[i]).start();
2 1. }
2 2. }
2 3. }

C) The first inbound datagram is handled, but all other datagrams are missed.
D) An IOException is thrown if there are no active connections.
