I have read something's, about static classes, mostly about that static classes are "evil" in Java, and I was wondering what does the Static calss actually do?
What are the applications to it Unity C#, and C# in general?

3why are they "evil" in Java exactly? It depends on the use. – Lotan May 27 '20 at 11:43

3Everything (`goto` included) can be good or evil. – Dmitry Bychenko May 27 '20 at 11:43

1@DmitryBychenko Although `goto` is hard to justify :) – MakePeaceGreatAgain May 27 '20 at 11:44

In Unity3d I recommend Scriptable Objects. – Panda Strong May 27 '20 at 11:45

@Lotan I have read some stuff like this, this one was just a question, but still https://stackoverflow.com/questions/7026507/why-are-static-variables-considered-evil But my question is not why about Java, more towards C# – Galactic_CakeYT May 27 '20 at 11:45

@PandaStrong but why? – Galactic_CakeYT May 27 '20 at 11:45

Note that the question you linked to is very old. These kinds of questions no longer are considered a good fit for SO, because their answers have to be based on opinion and thus they lead to discussion more than to subjectively correct answers. – Joachim Sauer May 27 '20 at 11:48

1. Changes during playn mode are preserved. 2. You can easily drag&drop them everywhere and get the same effect as static. 3. serialization – Panda Strong May 27 '20 at 11:50

@JoachimSauer Okay thanks, I just started to learn coding, so I don't know what is considered "old" or new – Galactic_CakeYT May 27 '20 at 11:51

@DmitryBychenko what is "goto" – Galactic_CakeYT May 27 '20 at 11:52

`goto` is a notorious statemed (now we use `if`, `switch`, `while`, `for`, `return` instead) which has been considered harmful by Dijkstra in year 1968 https://homepages.cwi.nl/~storm/teaching/reader/Dijkstra68.pdf – Dmitry Bychenko May 27 '20 at 11:56

1@PandaStrong Note that "Changes during play mode are preserved" won't be allways the desired behaviour for static classes. – Lotan May 27 '20 at 11:58

"The static modifier makes an item non-instantiable, it means the static item cannot be instantiated. If the static modifier is applied to a class then that class cannot be instantiated using the new keyword. If the static modifier is applied to a variable, method or property of class then they can be accessed without creating an object of the class, just use className.propertyName, className.methodName."
Static class basically means that there is just one instance of the object.
It can be good or bad, depends on what you need, for example if you have an int to store the player money you can use static int money and then get or set the variable
from anywhere, but if you want to create something multiple time (like enemies etc') you cann't use it.
