Making an object that can be various types?

I have a byte[] and a short[] used for the same thing. I want to switch from using the byte[] and short[] based on the maximum value needed, which changes occasionally. My idea is to have an Object that is swapped between referencing the byte[] or the short[] as needed. The part I can't figure out is casting the Object to the array type its referencing. I tried this to alter the contents of the array the object is referencing: ```java...

Minecraft plugin that displays text above a player's head

I have the queue, display, and deletion working, the only issue is that there can be multiple ArmorStands/Messages at once, regardless of the fact that I have a Map associating a single armor stand with a player. When the display function is called, it checks if there is an associated armor stand, and deletes it (before i get queue working, i want there to be one message displayed at a time) ``` public final Map<Player, ArmorStand> playerArmorStand = new HashMap<>(); ...

How to switch a JavaFXML project from JDK 22 to Java SE 8?

I have imported a project on NetBeans to analyze but all the classes come out as errors and such. The best Java version I can use is Java SE 8 which has JavaFX 8, but I don't know how to switch the platform for the project. I already installed OpenJDK 8u432 but the IDE can't recognize it to have JavaFX 8. Any help on that?

unable to import Gson java dependency to my Maven JavaFXML Project

I have imported a code for a Maven JavaFXML Project and can't add a Gson jar file to my project. it is a required dependency and right clicking the Java Dependency folder doesn't have any options to offer. I have installed the Gson jar file for use and I just need to add it to the project. Ignore the Gson in the 'Dependencies' folder as it was a solution that didn't help.

Unable to build a JavaFX code on NetBeans 17

I have installed and used JavaFX 21 on NetBeans 17 and wrote simple coding to build an interface. I ran the program but gave me an error saying that the program failed to build. My initial thought was that the versions are included in JavaFX 21 but I have my doubts. Someone recommended that I work with JavaFX 8 but I couldn't find a source to download it from. Either helping me to solve the error or to install JavaFX 8 would be appreciated.
