How to get the file correctly?

Question

Java

I do like this:

File cageFrom = new File(File.separator + "home" + File.separator + "SkyWarsUtils", "Cages");

Why is the error popping up

java.io.FileNotFoundException: /home/SkyWarsUtils/Cages (No such file or directory)

?

Answer 1

I figured it out myself an hour ago)
If the files are in the root of the project, remove the slash at the beginning.
You can also take files/streams from resources: + As Alexey already said, Path is more convenient. App.class.getClassLoader().getResource("filename")

Answer 2

It is not clear why you are inserting file.separator, you still have an absolute path. You can write at once: In your case you still call StringBuilder implicitly. But you can do even better - use a relative path: Such a file will refer to the Cages file in the project folder.
File file = new File("/home/SkyWarsUtils/Cages");
File file = new File("./Cages");
