MC	Which statement is CORRECT?	Static binding occurs at run-time whereas dynamic binding occurs at compile-time.	incorrect	Different subclasses of a parent class can all have different implementations of methods with the same name, number of parameters and parameter types. 	correct	In an inheritance structure with a parent-class "Animal" and sub-class "Chicken" at most 1 of these classes is allowed to have a method with name "makeNoise".	incorrect	Dynamic binding means that objects are allowed to take the form of either the class they are an instance of, or any of its sub classes.	incorrect	
MC	Which statement is CORRECT?	ODL is only optimized for Java objects.	incorrect	The extent of a class is the set of all current instances.  	correct	Unary, binary and ternary relationships are supported in ODL. 	incorrect	Many-to-many relationships cannot be expressed using ODL.	incorrect	
MC	Objects should be made persistent when...	you need them over multiple program executions.	correct	you only need them during 1 program execution, and then never again.	incorrect	
MC	Which statement is CORRECT?	Unary, binary and ternary relationships are supported in ODL. 	incorrect	The extent of a class is the set of all current instances.  	correct	Many-to-many relationships cannot be expressed using ODL.	incorrect	ODL is only optimized for Java objects.	incorrect	
MC	Which statement is NOT CORRECT?	Objects store both a piece of information and ways to manipulate this information.	incorrect	Objects are blueprints of classes. "Human", "Employee", "Sale" are examples of objects.	correct	A class can be instantiated into several objects.  	incorrect	Objects are instances of classes. The people "Bart Baesens", "Wilfried Lemahieu" and "Seppe vanden Broucke" could be instances of the class "Person".	incorrect	
MC	Which statement is CORRECT?	An object contains the blueprint description of all its characteristics.	incorrect	A class must have exactly one constructor.	incorrect	Many-to-many relationships cannot be expressed using ODL.	incorrect	Persistence by class implies that all objects of a particular class will be made persistent.	correct

MC	Objects should be made persistent when...	you only need them during 1 program execution, and then never again.	incorrect	you need them over multiple program executions.	correct	
MC	Which statement is NOT CORRECT?	Persistence by creation is achieved by extending the syntax for creating objects to indicate at compile-time that an object should be made persistent.	incorrect	Persistence by marking implies that all objects will be created as persistent.  An object can then be marked as transient at compile-time.	correct	Persistence by inheritance indicates that the persistence capabilities are inherited from a pre-defined persistent class.  	incorrect	Persistence by class implies that all objects of a particular class will be made persistent.	incorrect	
MC	Which statement is NOT CORRECT?	Encapsulation refers to storing a value variable, and making it impossible to retrieve it.	incorrect	Encapsulation refers to controlling the way a variable is accessed by forcing users to use getter/setter methods that prevent misuse of the variable.	correct	Encapsulation implies that the methods of a class are not accessible to the other classes. 	incorrect	Encapsulation refers to storing a value in a variable, and never changing it again. This way its value is safe forever.	incorrect
