Editing Comparison of C Sharp and Java (section)

=== Partial class ===
C# allows a class definition to be split across several source files using a feature called ''partial classes''. Each part must be marked with the keyword {{mono|partial}}. All the parts must be presented to the compiler as part of a single compilation. Parts can reference members from other parts. Parts can implement interfaces and one part can define a base class. The feature is useful in code generation scenarios (such as [[user interface]] (UI) design), where a code generator can supply one part and the developer another part to be compiled together. The developer can thus edit their part without the risk of a code generator overwriting that code at some later time. Unlike the class extension mechanism, a partial class allows ''circular'' dependencies among its parts as they are guaranteed to be resolved at compile time. Java has no corresponding concept.
