Code organization is the way how code is placed in a project.
Questions regarding code organization can deal with the topic on various levels:
How to split parts of a larger project in subprojects (e.g. in maven modules)
How to distribute classes in packages
Where to put tests relative to the code that gets tested
Where to put methods or fields inside of classes or other code units
One aspect of code organization is package-design.
