Packaging section could use a little more discussion

A couple of students in the 2020 Java Launchcode session had issues with packages while doing the exercises and studios (e.g. they will put their code in package A.B.C.myCode in the folder structure, but their package line in their code says "package myCode;") I see very little of it mentioned in the courseware (right here: https://education.launchcode.org/java-web-development/chapters/data-types/exercises.html#creating-a-package-and-classes) - shouldn't there be a little bigger discussion on it?

Here is a discussion that is pretty good:

Comece pela página de courseware vinculada na issue, especialmente pelo exercício “Creating a Package and Classes”, e revise a discussão referenciada do GeeksforGeeks para obter uma cobertura útil. Amplie a discussão sobre packaging para que a relação entre a estrutura de pastas e a declaração de package fique clara, incluindo a inconsistência relatada; considera-se concluído quando o exercício abordar essa confusão.
