Multiple classes in a single Java file, each with a main method - unexpected behavior?

Question

I have got the following code in a file called test.java which is located inside the directory C:\\D\\JavaProjects

class test
{
        public static void ma         


        

Answer 1

Presumably you're running on Windows, right?

That means you can't have two classes which differ only in case - because they'll both end up wanting to be in the same file, as Test.class and test.class are effectively the same filename in case-insensitive file systems.

It's not really a bug in Java - just an unfortunate but natural corollary of using a case-insensitive file system in conjunction with a language which attaches meaning to filenames.
