Partial Class (Java and C# Cross Reference Guide)

A partial class, or partial type, is a class that can be split into two or more source code files and/or two or more locations within the same source file. Each partial class is known as a class part or just a part. Logically, partial classes do not make any difference to the compiler. The compiler puts the class together at compile time and treats the final class or type as a single entity exactly the same as if all the source code was in a single location.

Languages Focus

For languages that have implemented partial classes, you need to know usage details and restrictions. Can you split a class into two or more files? Can you split a class within a source code file into two or more locations? What are the details of inheritance? Does it apply to interfaces as well?

Java:  "Partial Classes" Not Supported	C#:  "Partial Classes" partial C# uses the keyword partial to specify a partial class. All parts must be in the same namespace. Syntax Example: class partial Cyborg: System.Object { }  C# Partial Classes (partial)
