如何在eclipse项目中有2个同名文件但在2个不同的子文件夹中？

Question

Right now I have a set up like this:

...\\lab18\\18a\\18a.java

...\\lab18\\18a\\monster.java

and

...\\lab18\\18b\\18b.java

...\\lab18\\18b\\monster.java

the issue is the 2 'monster.java' files in the 18a and 18b sub-folders, is there a way to keep these names the same but not cause errors on the 'monster.java' in the 18b, 18c, etc sub-folders? The error eclipse is stating is that Monster is already defined referencing to the .java file in the 18a folder.

here is a screenshot of what I'm referring to:

Here is a screenshot of how the files and folders are organized in Windows explorer:

Answer 1

Same source folder, two packages:

---

Package declaration in the Java classes

-> Same project, same source folder, different packages, same class name.

Answer 2

You have put them into the same package (default package) within two different source folders. The only way you will be able to have two classes with the same name is if they are in different packages.

For example, for lab18 one, put it into a subfolder called lab 18a and put lab18b into a subfolder called lab18b

lab18_oop_interfaces
  lab18a
    lab18a
      Lab18a.java
      Monster.java
  lab18b
    lab18b
      Lab18b.java
      Monster.java

Alternatively, put both the subfolders into one src folder and mark that as the source folder:

lab18_oop_interfaces
  src
    lab18a
      Lab18a.java
      Monster.java
    lab18b
      Lab18b.java
      Monster.java
