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...

A patient has a known BBT diagnosed after 1/01/04 and it is not treated. After time, the patient is diagnosed with a malignant brain tumor in the same site. Response: Report as two primaries one benign (sequence number 60) and one malignant (sequence number 00). Once a tumor transforms from benign to malignant, another abstract for the malignant tumor is prepared. 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...

The MVC design pattern is very simple to understand but much more difficult to live with. You just need this little bit of Business Logic in the View logic or you need just that little bit of View logic in the Business tier and pretty soon you have a real mess. Making ActionForm a class takes advantage of the single inheritance restriction of Java to it makes it more difficult for people to do things that they should not do. See similar questions...

It must provide all of the methods in the interface and identify the interface in its implements clause. 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...

The scenario is a set of several tasks united for sequential execution. If you wish to add a scenario to the task list, you should have at least one task already added to the program. Service Center for MySQL allows you to add a new, edit, change scheduler options, execute, and delete a scenario See similar questions...

A scenario is the Trainz version of Microsoft Train Simulator's "activity." Both are a set of tasks for you, the engineer, to complete. In use, the instructions are displayable while driving. It's possible to create your own activity or scenario; both are somewhat involved. MSTS has a built-in activity function, whereas Trainz requires some knowledge of scripting. The TrainzProRoutes group has created a utility that aids in the creation of scenarios. [Back to FAQs] 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...
