I\'ve been ask开发者_JAVA百科ed a question. It is the following: The API documentation of an abstract class tells you whether a method
So here\'s what I have: 1 interface called Set 1 abstract class which implements set 2 classes which extend the abstract class, called ArraySet and ListSet
I\'m trying to be lazy and implement the cast operators in the abstract base class rather than in each of the derived concrete classes.I\'ve managed to cast one way, but I\'m unable to cast the other.
In the following code, I create a base abstract class Base. I want all the classes that inherit from Base to provide the name property, so I made this property an @abstractmethod.
Say we have an interface as such... interface ICalculator<T extends CalculableObject>{ void calculate(T obj);
Given the classes below: public class Address : Place { public virtual string Street { get; set; } public virtual int Number{ get; set; }
In java can inner classes inherit from an abs开发者_运维技巧tract class defined outside of the inner class\'s outer class?
as I found, an abstract class is an interface when it has zero implementation in it. am I right开发者_StackOverflow ?
Have a very interesting situation and can\'t seem to find anything concrete on the webs surrounding reflection, inheritance and generics.
I have half a dozen classes which all extend the same abstract class. The abstract class has a static variable pointing to some JNI code that I only want to load once per instantiation of the classes.
