My VS code will not see files within the same package

I coudn't find the visual studio tag but essentially in VS code, whenever I have files declared within the same package, for example package Test; It won't says other files within that package don't exist. For instance, if I have files of Shape.java and Circle.java in the the package Test, and call an object of circle or an object of shape in my main method file, it returns errors saying that those objects and files don't exist. Please any help would be appreciated I've been dealing with this problem for years and I couldn't find any soltuions online. It's ruined many projects since I needed to declare everything in the default package (files not in any pacakges) which causes errors for certain projects. I can also re explain or provide screenshots if nessecary.
