Newbie: Java Import and compile statement

[Rachel]

Hi,

1. I have 3 files:

c:\folder1\folderA\file1.java // no package statement inside
c:\folder1\folderA\file2.java // no package statement inside
c:\folder1\folderB\file3.java // package folderB;

2. I've compiled file1 & file 2:
c:\folder1\folderA> javac *.java
So, c:\folder1\folderA contains file1.class & file2.class

3. Now, I want to import file1.class & file2.class from c:\folder1\folder11.

Question:
a. What should the import statement be in file3.java?
b. In C:\folder1\folderB, what should the javac statement be for file3.java?

Thanks much,
Rach

javac -classpath
c:\folder1\folderA\file1.class;c:\folder1\folderA\file2.class

That's your first mistake then. Always use packages, and always have
your source layout matching the package layout.

import file1;
import file2;

This is incorrect and is now officially wrong. You cannot import from the
unnamed package.
Place all classes in a package from now on. Only use unnamed code for quick
tests and minimal demos.
