Some more Mock questions #1 For me

[Mark Spritzler]

Here are 20 more questions that I came up with. I hope they are right. If not just post why they are wrong and how to fix them and I will fix them

1. Which method(s) can be called to get the MIDP specification?
A. System.getAppProperty("MicroEdition-Profile");
B. System.getProperty("microedition.profiles");
C. System.getProperty("MicroEdition-Profile");
D. MIDlet.getProperty("microedition.profiles");
E. MIDlet.getAppProperty("MicroEdition-Profile");
2. Which Specification(s) will you not find a DataSource available?

Runnable {

MyMidlet(){
myForm = new Form("SCMAD Mock Exam");
exitCommand = new Command("Exit",Command.EXIT, 0);
myString = new StringItem("12");

myForm.append(myString);

myForm.addCommand(exitCommand);
myForm.setCommandListener(this);

}

public void startApp(){
mDisplay = Display.getDisplay(this);
mDisplay.setCurrent(myForm);
}

public void commandAction(Command c, Displayable s) {
destroyApp(false);
            notifyDestroyed();
}

}

}

public void destroyApp(boolean unconditional){
}

}

A. Will Not Compile

C. Shows 12 on the devices screen
D. Displays nothing
E. Fails to install

A. MIDlet-<n>
B. MIDlet-Push-<n>
C. MIDlet-Vendor
D. MIDlet-Name
E. MIDlet-Description
When Installing a MIDLet a code is returned. Place Each Code with its
corresponding message
(might not be that specific on test, I hope not)
8. 900A. Attribute mismatch
9. 904B. Invalid Jar
10. 905C. Success
11. 907D. Push Registration Failure
12. 911E. Jar Size Mismatch
13. Is the Timer class Thread-safe?
A. True
B. False
For the following use
A = Mandatory
B = Conditional
C = Minimum
D = N/A
According to the JTWI specs, the following specifications are one of
the
four above
14. MMAPI
15. MIDP 2.0
16. CLDC 1.1
17. CLDC 1.0
18. WMA 1.1

19. Select all that are true regarding RecordStores.
A. When updating a record, another user can update the same record at
the
same time.
B. All RecordStore operations are atomic, synchronized, and serialized
C. If there is no RecordStore when calling
RecordStore.openRecordStore("MyRecords", true)
a RecordStoreNotFoundException is thrown
D. A call to RecordStore.deleteRecord will allow the recordID to be
reused
E. RecordStoreNames are case-sensitive and cannot exceed 32 characters.
20. Assume you have two MIDlet suites that are sharing a RecordStore.
MIDletA created the records store.

What are the results of the following code. Assume all interface
methods are correctly
implemented and the form and commands are already being
displayed.
the user selected the Delete command object

    public class MIDletB extends MIDlet 
        implements CommandListener, Runnable {

        private Display myDisplay;
private Form myForm;
private Command deleteRecordStore;
private Command exitRecordStore;

private RecordStore sharedRecords;

public MIDletB(){
    try {
sharedRecords = RecordStore.opeRecordStore 
                    ("BankAccounts", "VendorName", "MIDletASuite");
    } catch (Exception e) {
  // Do some exception handling here
    }
}

        public void commandAction(Command c, Displayable s) {
    if (c == deleteRecordStore) {
try {
            RecordStore.deleteRecordStore("BankAccounts");
} catch (Exception e) {
    // Do some exception handling here
 }
    }

    ...
}
    }

A. The shared RecordStore called BankAccounts is deleted from the
mobile
device.
B. The shared RecordStore called BankAccounts is deleted from MIDletB
Suite
only
C. The shared RecordStore called BankAccounts still exists, but all the
records are deleted.
D. An RecordStoreException is thrown in the openRecordStore() call.
E. An RecordStoreException is thrown in the deleteRecordStore() call.
F. An RecordStoreException is thrown in the deleteRecordStore() call
because
the vendor and suite name is missing in the parameters.
Answers will be in a seperate thread.

Good Luck

I am going to make up some more tomorrow, but won't be able to post them till Friday night, because I can't access Javaranch from work, and I go to the gym tomorrow night.
Good Luck

Many thanks!!!

Thank you Mark! What a Mock!

suggestion to question #1:
E. MIDlet.getAppProperty("MicroEdition-Profile");
since the "getAppProperty" is NOT a STATIC method of "MIDLet" class, you'd better put a snippet to make clear, like this:
public class hellocommand extends MIDlet{
public getMIDPVersion()
{
System.getAppProperty("MicroEdition-Profile");//1
System.getProperty("microedition.profiles");//2
System.getProperty("MicroEdition-Profile");//3
MIDlet.getProperty("microedition.profiles");//4
MIDlet.getAppProperty("MicroEdition-Profile");//5
this.getAppProperty("MicroEdition-Profile"); //6
}
}
this way "//5" is compile error, and "//6" is ok.
Too difficult to answer maybe.

question #3:
"... class MIDlet, implements" comma is BUG.
and
myString = new StringItem("12");will NOT compile
your answer is run well, why?
