A programmer decides to make the static DEFAULT_DSCR mutable, removing its final status, as in: static public String DEFAULT_DSCR = "(generic phone)";
A mutator is added for this member. Any String whose length is at least 2 characters will be acceptable as a new DEFAULT_DSCR.
Check the true statements (there may be more than one correct answer):
A. If the mutator takes a String parameter, newDefault, a reasonable definition would be:
if ( newDefault. length() < 2 )
{
this. newDefault = DEFAULT_DSCR;
return false;
}
this. newDefault = newDefault;
return true;
B. If the mutator takes a String parameter, newDefault, a reasonable definition would be:
if ( newDefault. length() < 2 )
return false;
DEFAULT_DSCR = newDefault;
return true;
C. The mutator for this member will be an instance method.
D. If the mutator takes a String parameter, newDefault, a reasonable definition would be:
if ( newDefault. length() > 0 )
return false;
DEFAULT_DSCR = newDefault;
return true;
E. The mutator for this member will be a static method.
