  2. Method overriding - Wikipedia

    en.wikipedia.org/wiki/Method_overriding

    C++ does not have the keyword super that a subclass can use in Java to invoke the superclass version of a method that it wants to override. Instead, the name of the parent or base class is used followed by the scope resolution operator. For example, the following code presents two classes, the base class Rectangle, and the derived class Box.

  3. Comparison of C Sharp and Java - Wikipedia

    en.wikipedia.org/wiki/Comparison_of_C_Sharp_and_Java

    C#, unlike Java, allows the use of lambda functions as a way to define special data structures called expression trees. Whether they are seen as an executable function or as a data structure depends on compiler type inference and what type of variable or parameter they are assigned or cast to.

  4. Method (computer programming) - Wikipedia

    en.wikipedia.org/wiki/Method_(computer_programming)

    For example, an object can send an area message to another object and the appropriate formula is invoked whether the receiving object is a rectangle, circle, triangle, etc. Methods also provide the interface that other classes use to access and modify the properties of an object; this is known as encapsulation. Encapsulation and overriding are ...

  5. C Sharp (programming language) - Wikipedia

    en.wikipedia.org/wiki/C_Sharp_(programming_language)

    When implementing multiple interfaces that contain a method with the same name and taking parameters of the same type in the same order (i.e. the same signature), similar to Java, C# allows both a single method to cover all interfaces and if necessary specific methods for each interface. However, unlike Java, C# supports operator overloading. [90]

  6. Double dispatch - Wikipedia

    en.wikipedia.org/wiki/Double_dispatch

    Double dispatch is useful in situations where the choice of computation depends on the runtime types of its arguments. For example, a programmer could use double dispatch in the following situations: Sorting a mixed set of objects: algorithms require that a list of objects be sorted into some canonical order. Deciding if one element comes ...

  7. Boxing (computer programming) - Wikipedia

    en.wikipedia.org/wiki/Boxing_(computer_programming)

    C# doesn't support automatic unboxing in the same meaning as Java, because it doesn't have a separate set of primitive types and object types. All types that have both primitive and object version in Java, are automatically implemented by the C# compiler as either primitive (value) types or object (reference) types.

  8. Function overloading - Wikipedia

    en.wikipedia.org/wiki/Function_overloading

    For example, to have a derived class with an overloaded function taking a double or an int, using the function taking an int from the base class, in C++, one would write: class B { public : void F ( int i ); }; class D : public B { public : using B :: F ; void F ( double d ); };

  9. Comparison of C Sharp and Visual Basic .NET - Wikipedia

    en.wikipedia.org/wiki/Comparison_of_C_Sharp_and...

    Both C# and VB.NET have high adoption rates, and very active developer communities and Microsoft fully supports both communities. .NET framework developers widely use both VB.NET and C# as primary languages. [17] [18] However, C# has more community activity on the Internet and there are more books available for C#. This may indicate either that ...
