Java equivalent to #region in c#

Is there something in Java that would allow for structuring the source code as it is done in C# with the pre-processor directives

#region

and

#endregion

?

No, there is nothing equivalent.

Code folding is an IDE feature, not a language feature.

Eclipse has code folding for classes and members when Java files are loaded in it. It may be extended (for example) to add code folding on carefully crafted comment lines.

No, there's no built-in solution to that.

However there are some Java IDE's which support folding for certain comment-patterns. And of course all IDE's support folding the code by classes, methods etc.

region is a language feature and NOT an IDE feature. Specifically, it is part of the C# programming language and Visual Studio knows how to interpret it.

Not as such. Bear in mind that these preprocessor directives are more for VS's benefit than they are a part of the C# or VB language spec. Preprocessor directives in Java would be the IDE's business.
