abstract data type in .net

Question

what is Abstract Data Type

Vulpes · Answer

Well, an abstract data type (not to be confused with an abstract class) is a model for building a class of data structures which have similar behavior. Abstract data types include stacks, queues, lists and sets. The abstract data type specifies what operations should be provided by an implementation of that data type without actually implementing it. For example a stack should have push, pop and top operations and a queue should have enqueue and dequeue operations. The methods which implement these operations do not necessarily need to have the same names. .NET provides implementations of several abstract data types including Stack , Queue , List and HashSet .

we can create abstract as class or method abstract class contain abstract as well as non abstract method abstract is incomplete class,which is implemented by using derived class some of its method may have implementation while those dont have implementation can be implemented by derived class. abstarct classes are private by default. abstract class can have access modifiers,i.e public, private etc abstract class can contain data fields. class can inherit from multiple interfaces at the same time while class cant inherit from multiple classes at the same time.
