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:

從 issue 中連結的 courseware 頁面開始，尤其是「Creating a Package and Classes」練習，並查看所參考的 GeeksforGeeks 討論，以取得有用的涵蓋內容。擴充關於 packaging 的討論，讓資料夾結構與 package 宣告之間的關係更加清楚，包括已回報的不一致；完成的標準是該練習能夠處理這項困惑。
