Putting Nested Classes In Separate Files

Question

I have a file with nested classes, but it\'s becoming long enough to be unreadable. Is there a way I can break out the nested classes into separate files?

Answer 1

Write unit-tests to cover the code you are going to refactor.

Then use refactoring tools, e.g. Eclipse/JDT to extract each class. Run the tests for each refactoring job.

For extra fun, you can do this without the unit tests.
