Question

Ok really stupid question, but I have some methods defined in a file called x.java, which is in the default folder, and in the same folder, I have a file called z.java. I want to use the functions defined in x in z. When I try, it tells me the function is undefined. I tried to put import x.java; but it says x.java cannot be resolved. What am I missing here?

Based on your description, I’d bet there’s a good chance both of your source files defined classes in the default package (i.e., you don’t explicitly define a package for them).

You can’t import a class that’s in the default package.

Recommend you put your class x in a named package (e.g., foo.bar.x), then you can import it:

import foo.bar.x;
