1- In
JAVA the convention is to name packages with a starting
lower case letter.
2- It is also the convention to name classes with a starting
upper case letter.
3- For the JAVA class files that are located in folders or archives, their location in
the folder's hierarchy must follow their package names:
class a.b.c.D ( class D in the package a.b.c ) must have its file located like this:
a/b/c/D.class
So:
a- Rename 'fileLister.java' to 'FileLister.java'
b- Rename 'fileListerTest.java' to 'FileListerTest.java'
c- Edit the 'FileLister.java' file so it should read:
d- Edit the 'FileListerTest.java' file so it should read:
e- From the current root folder of this JAVA project, create a sub-folder 'fileLister'
f- Move the 2 .java files into that sub-folder.
g- From the current root folder of this JAVA project, do the following commands:
> javac fileLister/FileLister.java
> javac fileLister/FileListerTest.java
