No, not quite. An abstract class in C++ cannot be instantiated, but it can (and often does) contain implementation code and/or data members. A C# interface cannot contain any implementation code or data members - it is simply a group of method names & signatures. A C# interface is more like a COM interface than a C++ abstract class.

Latest Answer: hi, Diff b/w abstract class and interface are.. Abstract class can have concrete me... Latest Answer: See the base class(super class) of all classes is Object class.Other wise when u creat a class ,and ... See similar questions...

The principal difference is that an abstract class is used when you have a type/subtype relationship. An interface does not imply a type/subtype hierarchy; it merely forces a class to have some methods with a given signature. That allows some other code to rely on being able to call those methods. You want to subclass abstract classes when you are making subtypes that define the abstract behavior. The subclass should have a "kind of" relationship to the superclass. See similar questions...

abstract value is a mathematical abstraction of some bits that might exist in your computer. (It's an abstraction in the same sense that a road map of the United States is an abstraction of the geography and roads of the United States.) In a Larch BISL's model of your computer, each variable contains an abstract value. See similar questions...

No. Since abstract classes don't have constructors it would be a syntax error to call super(). Just implement the constructor of the subclass as if it does not have a parent class. See similar questions...

The ResourceBundle class is used to store locale-specific resources that can be loaded by a program to tailor the program's appearance to the particular locale in which it is being run. The exception propagates up to the next higher level try-catch statement (if any) or results in the program's termination. See similar questions...

abstract is a history of the title to a particular tract of land. It is not a title! It consist of a summary of the material parts or recorded instruments affecting the title of the real estate. The abstract may be correct but the title imperfect. The abstract is not a guarantee. It is only a record of what has been recorded. It does not judge the correctness of any item it lists. It merely reports them for an examiner to interpret. See similar questions...

Maybe nothing, you might own Torrens property. Property is either classified as Torrens or Abstract. While Abstract property requires a compendium of all pertinent documents ever recorded against a property, Torrens property starts over with every new owner. Also know as registered property, Torrens is a system whereby each new owner is issued a separate certificate showing that they own the real estate. If your property is Torrens you do not need an abstract to sell the property. See similar questions...

You need a special form of IMPLEMENT_SERIAL that looks like this: Use the regular DECLARE_SERIAL but use IMPLEMENT_SERIAL_ABC shown below instead of IMPLEMENT_SERIAL. #define IMPLEMENT_SERIAL_ABC(class_name, base_class_name, wSchema) _IMPLEMENT_RUNTIMECLASS(class_name, base_class_name, wSchema, NULL) CArchive& AFXAPI operator>>(CArchive& ar, class_name* &pOb) { pOb = (class_name*) ar.ReadObject(RUNTIME_CLASS(class_name)); return ar; } See similar questions...

abstract class cannot be instantiated. Only its subclasses can be instantiated. You indicate that a class is abstract with the abstract keyword like this: Abstract classes may contain abstract methods. A method declared abstract is not actually implemented in Abstract methods may only be included in abstract classes. However, an abstract class is not required to have any abstract methods, though most of them do. See similar questions...

On-line abstract submission will be available in the fall of 2007. Please check this website for additional information. See similar questions...

Because the focus is on abstraction. Let developers worry purely about what their application does, instead of how the underlying system implements various details (like menubars, window titlebar widgets, scrollbars, etc.). The full name is Daylon Abstract, since my company started the project and currently maintains it. See similar questions...

This is a good question, although there's no hard-and-fast answer to it. To help you in deciding whether a specification is sufficiently abstract, we'll give you a checklist, and an example of what not to do. See similar questions...
