  B. The records that match the search criteria in RecordFilter will be returned using the ordering defined by RecordComparator.
  C. All records will always be available as part of the enumeration result set.
  D. The return order of the result set is undefined.

  A. For a given enumerator, multiple filters can exist.
  B. For a given record store, multiple comparators can exist.
  C. The RecordStore class provides a method that returns a list of record stores in the MIDlet suite.
  D. A record store's authorization mode can be set only when the record store is created.

• Question 43:

  Given:

  50.

  class MyGameCanvas extends Canvas {

  51.

  //...

  60.

  public MyGameCanvas() {

  61.

  int width1 = getWidth();

  62.

  int height1 = getHeight();

  63.

  //...

  70.

  setFullScreenMode(true);

  71.

  //...

  80.

  int width2 = getWidth();
