Code folding in Eclipse

Eclipse supports code folding.

Go to workbench preferences -> General -> Editors -> Structured Text Editors, and check the "Enable folding" box.

Then go to workbench preferences -> Java -> Editor -> Folding, and adjust your folding preferences.

The <editor-fold and #region can be used as a block folding wrapping anything you want, including not just a function or a comment but both or even multiples functions, comments, variables, etc.

Eclipse does not has such functionality. I am using Eclipse Neon and still missing this.

Windows->Preferences->(C/C++)->Editors->Folding

(C/C++) will change based on the language you are using. Generally each language plugin will have its own folding options
