The short answer is no, that's not how classpath directories work.

Each classpath directory is regarded as the root of a package structure. Each package is a directory within the root. So, javac will do so automatically if aa is a package directory and a is the root. You're classes would look like this:

/a/A.java

class A {}

/a/aa/AA.java

package aa;
class AA {}

/b/B.java

package b;
import aa.AA;

class B {
  private AA aaInstance;
  private A aInstance;
}

Because A has no package, it's placed in the root package.

Otherwise, you have to set each source dir explicitly.

Method in Java to create a file at a location, creating directories if necessary?

I am attempting to write a file using java.io, where I am trying to create it at the location "some/path/to/somewhere/then-my-file".
