Overloading (Java and C# Cross Reference Guide)

By Mike Prestwood

Java versus C#: A side by side comparison between Java and C#.

 
Language Details
 

Language Details is kind of a catch all for stuff that didn't make it into language basics nor any other category.

Overloading

[Other Languages] 

Types of overloading include method overloading and operator overloading.

Method Overloading is where different functions with the same name are invoked based on the data types of the parameters passed or the number of parameters. Method overloading is a type of polymorphism and is also known as Parametric Polymorphism.

Operater Overloading allows an operator to behave differently based on the types of values used. For example, in some languages the + operator is used both to add numbers and to concatenate strings. Custom operator overloading is sometimes referred to as ad-hoc polymorphism.

Java: 

Java Overloading

  • Operator - No. Sun deliberately chose not include operator overloading in the Java language.
  • Method - Yes.
C#:   implicit

C# supports both method and operator overloading.

For methods, C# supports implicit overloading (no need for an overload keyword).
