10.public void startApp(){ 

11.Float f = new Float(3.14); 

12.System.out.println("Pi: " + f); 




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

Answer: C 

Q142. - (Topic 1) 

Given the MIDlet code: 

10. //... 


 try { 


 Connection conn = Connector.open("http://www.sun.com"); 


 InputStream is = conn.getInputStream(); 




 } catch (IOException e) { 



40. } 

Which is true? 

A. Compilation fails. 

B. The system returns a null InputStream. 

C. The system returns a valid InputStream for reading. 

D. An exception is thrown at runtime. 

Answer: A 

Q143. - (Topic 2) 

Which two are true regarding the interaction of the Application Management Software (AMS) and a MIDlet when a connection notification is pushed to a device? (Choose two.) 

A. If the notification is for a datagram, the AMS must guarantee that the datagram is made available to the MIDlet after the MIDlet is invoked. However, additional datagrams could be lost during the time required to start the MIDlet. 

B. If the AMS starts a MIDlet in response to an inbound connection, the MIDlet must defer the responsibility of closing the connection to the AMS to prevent an IOException from occurring. 

C. There are no guarantees provided by the AMS as to the state of a datagram or socket connection. The connection notification is intended to start the MIDlet to handle subsequent connections. 

D. If the notification is for a socket, the connection must be provided to the MIDlet. However the server side of the connection may timeout before the MIDlet actually starts. 

Answer: A,D 

Q144. - (Topic 3) 


A record store has three records: Record 1 contains Apple, Record 2 contains Mango, Record 3 contains Cherry, and the RecordComparator class: 


 public class CompareTest implements RecordComparator { 


 public int compare(byte[] rec1, byte[] rec2) { 


 String str1 = new String(rec1), str2 = new String(rec2); 


 int result = str2.compareTo(str1); 


 if (result == 0) 


 return RecordComparator.EQUIVALENT; 


 else if (result < 0) 


 return RecordComparator.PRECEDES; 




 return RecordComparator.FOLLOWS; 





What is the return order of the records for an enumerator using CompareTest? 

A. Apple, Mango, Cherry
