Package/directory conventions in Java

Question

I want to use christophel.joel as my root package until I get a domain name. Which of the following is a better practice?

• Different set of christophel and joel folders for each project

  Example: \\Project Name\\christophel\\joel\\subdirectory\\ClassName.java

-OR-

• Only one set of christophel and joel folders

  Example: \\christophel\\joel\\projectname\\subdirectory\\ClassName.java

Answer 1
