Eclipse generates Java class filename conflict for inner classes

Question

I have two top-level classes; each has an inner class with the same name:

    **A.java**
    public class A
    {
    }
    class TestCase
    {
    }

    **B.java**
    public class B
    {
    }
    class TestCase
    {
    }

My expectation is that I will wind up with four class files, including A$TestCase.class and B$TestCase.class, which is what I get when I compile from the command line. Eclipse, however, just creates TestCase.class, and declares that "The type TestCase is already defined" when I try to compile B.java.

Is there an Eclipse option that I can set to produce (what I believe is the standard) A$TestCase.class and B$TestCase.class?

Thanks.

By the way, I am using Luna: Version: Luna Release (4.4.0) Build id: 20140612-0600

Why not declare a `TestCase` interface or abstract class and implement it for both `A` and `B`? — Alexis Leclerc, Oct 01 '14 at 20:20

Both versions of TestCase are top level classses. You need to create inner classes

public class A {
    class TestCase {
    }
}

OK, it's not an inner class (which is another question I've had for a while: what is it called?). Nevertheless, the Java compiler, invoked from the command line, produces A$TestCase.class and B$TestCase.class. How can I persuade Eclipse to do the same thing? – Jack Straub Oct 01 '14 at 21:28
Eclipse will produce the same "dollar files" as the command-line compiler – Reimeus Oct 01 '14 at 21:38

It doesn't do this for me. It creates an A$TestCase.class and a B$TestCase.class, as it should.

But this is only when they're actually inner classes... in your case, they're not really inner classes at all.

TestCase is not an inner class as you might think, and this is why formatting code is essential when coding. check this
