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:

Issue にリンクされている courseware ページ、特に「Creating a Package and Classes」の演習から始め、参考として示されている GeeksforGeeks の議論を確認して有用な内容を取り入れてください。フォルダー構造と package 宣言の関係が明確になるように packaging の説明を拡充し、報告されている不一致も含めてください。演習でこの混乱を扱えれば完了です。
