Java switch enum的問題，透過圖書和論文來找解法和答案更準確安心。 我們找到下列懶人包和總整理
Java switch enum的問題，我們搜遍了碩博士論文和台灣出版的書籍，推薦曾瑞君寫的 OCP：Java SE 11 Developer 認證指南（上）物件導向設計篇 和洪錦魁的 C最強入門邁向頂尖高手之路王者歸來都 可以從中找到所需的評價。
另外網站Featured enum instead of switch - Java Code Geeks - 2023也說明：#Enum has some advantages. 1. The code looks better organized. 2. Each instance exists exactly once. This is guaranteed by JVM. 3. values() ...
這兩本書分別來自博碩 和深智數位所出版 。
國立臺灣大學 資訊工程學研究所 陳俊良所指導 楊騏嘉的 可繼承的JAVA列舉 （2008），提出Java switch enum關鍵因素是什麼，來自於列舉、JAVA、繼承、編譯器、class、Enum、物件。
最後網站C# Replacing switch(enum) flow control with Reflection則補充：The place where enum begins to loose its usefullness is when they get used for program flow control inside a switch statement.
OCP：Java SE 11 Developer 認證指南（上）物件導向設計篇
為了解決Java switch enum 的問題，作者曾瑞君 這樣論述：
Oracle公司繼Java 8推出1Z0-808與1Z0-809認證考試科目後，原本在次一個長期支援版本的Java 11也推出1Z0-815與1Z0-816的雙考試，但在2020/10/01之後，改以1Z0-819取代前兩者，成為現行要取得「Oracle Certified Professional: Java SE 11 Developer」證照的唯一考試科目。 雖然由兩科考試合併為一科，但考試範圍並未縮減。作者依據原廠公布的命題範圍，深入研讀相關文件，推出上、下兩冊認證指南，分別是： ✪OCP：Java SE 11 Developer認證指南（上） －

可繼承的JAVA列舉
為了解決Java switch enum 的問題，作者楊騏嘉 這樣論述：
Java 1.5加入許多新功能，包含enumeration。Java內部將enumeration做成class的形式，使得其constants就為instances，有著更強大的支援，附帶有variable、method等功能，不再只是單純的數字。但在class的條件之下，enumeration卻不行使用繼承的用法，以致與Java的核心概念有所衝突。因此本論文試著提出可繼承的Java enumeration，讓enumeration更為彈性，並且可在不更動Virtual Machine的前提之下能夠執行。
