I went through some of topics, but didn't find a proper anser. I'm trying to import class to other class, but I get "The import "classname" cannot be resolved" error. Both classes are in the same package. What can cause the problem? I also tried to clean my project.

In Java, you do not need to add import statements for classes that exist within the same package (they are actually automatically “imported” by the compiler).
Classes and interfaces in the same package can use each other without prefixing their names with the package name. But to use a class or an interface from another package, you must use its fully qualified name, that is, packageName. anySubpackageName. ClassName .
Yes, you can import a class twice in Java, it doesn't create any issues but, irrespective of the number of times you import, JVM loads the class only once.
If both classes are in same package, you don't have to import it.
