Two Packages in the Same Directory?

[marc weber]

The following is question #58 from Marcus Green's 1.2 Mock Exam No. 1.
(Note that two separate files are illustrated in the code.)

SOURCE: http://www.jchq.net/mockexams/exam1.htm

/*
You have these files in the same directory.
What will happen when you attempt to compile and run Class1.java if you
have not already compiled Base.java?
*/
 
//Base.java (FIRST FILE)
package Base;
class Base{
    protected void amethod(){
        System.out.println("amethod");
    }//End of amethod
}//End of class base
 
//Class1.java (SECOND FILE)
package Class1;
public class Class1 extends Base{
    public static void main(String argv[]){
        Base b = new Base();
        b.amethod();
    }//End of main
}//End of Class1
 
/*
1) Compile Error: Methods in Base not found.
2) Compile Error: Unable to access protected method in base class.
3) Compilation followed by the output "amethod".
4) Compile error: Superclass Class1.Base of class Class1.Class1 not found.
*/

The answer is 4, with the explanation, "Using the package statement has an effect similar to placing a source file into a different directory. Because the files are in different packages they cannot see each other..."

I'm fine with the answer (4), but I'm questioning the justification provided: "Using the package statement has an effect similar to placing a source file into a different directory." Since these files are each supposed to be in their own package, aren't they required to be in different directories?

To me, the "similar to" wording would be applicable if both files were in a directory called "Class1," and the Base file didn't declare a package at all. But as the question reads, the problem here is more than just package declaration.

Am I reading too much into this, or am I missing something?

I tend to agree. Maybe "effect of" would have been a better choice than "effect similar to".

I guess Marcus will be around to beat us up

PS: Why is my original post so wide -- extending horizontally off the screen?



I tried saving it as a simple text file to get rid of any weird paragraph formatting, then re-pasting it, but it's still doing it. (Or is it just my browser?)

Within [C0DE][/C0DE] tags there is no automattic wrapping. So you have to keep your lines short.

Ah... Thank you!
