Exam 9: Object-Oriented Programming: Classes and Objects

The keyword _______ indicates that the method overrides an existing method with the same signature.

Primitive-type variables refer to objects in a Visual Basic app.

While shadowing,programmers could use the This keyword and the dot separator to access the instance variable.

The Me reference is used implicitly to refer to the instance variables,properties and methods of an object.

Each class you create becomes a new type that can be used to declare variables and create objects.

If you write the code Public Property Hour As Integer,the compiler would generate property code that would use the Private instance variable __________.

Me can be used to distinguish between a local variable and an instance variable that share the same name.

A primitive-type variable can store exactly one value at a time,whereas one object can contain many individual pieces of data.

Failure to release resources when the program is no longer using them can cause .

A class can be used to create an instance of the class called a(n)________.

To access a Private Shared class member when no objects of the class exist,a Public Shared method or property must be provided.

Shared class members are available only after the first object of that class is created

Shared class variables have:

Programmers are encouraged to use method-parameter names that that are the same as instance variable names.

Each object of a class has its own copy of all the instance variables of the class.

Value types normally represent single pieces of data.

Object initializers (which initialize an object and its properties)use what keyword?

A constructor method is invoked each time an object of the class is instantiated.

Only certain objects have a Me reference.

A ReadOnly property provides only a __________ accessor.
