Editing Comparison of C Sharp and Java (section)

==== Generator methods ====
{{further|Generator (computer programming)}}
Any C# method declared as returning {{mono|IEnumerable}}, {{mono|IEnumerator}} or the generic versions of these interfaces can be implemented using {{mono|yield}} syntax. This is a form of limited, compiler-generated continuations and can drastically reduce the code needed to traverse or generate sequences, although that code is just generated by the compiler instead. The feature can also be used to implement infinite sequences, e.g., the sequence of [[Fibonacci numbers]].

Java does not have an equivalent feature. Instead, generators are typically defined by providing a specialized implementation of a well-known collection or iterable interface, which will compute each element on demand. For such a generator to be used in a ''for each'' statement, it must implement interface {{Javadoc:SE|package=java.lang|java/lang|Iterable}}.
