Thread: Using methods of one package in another package in same application? To import or not?

Salaam all!

I have an interface declared as "public" in a package called "package1". I want to use its methods in another package "package2" so do I have to import the package1 in the package2 ? both are in the same application

What happened when you tried without the import? Was there an error or did it compile?

Yes we need to import. Only when its imported then comes the part whether it can be accessible depending on the visibility(private, public, protected)

Yes without importing the netbeans editor shows a message that "add import for package1.<interface name>"

--- Update ---

but I read that with default modifier( no modifier) we can only access an interface in the same package but with public it can be accessed by any package? Can you explain this please

Sometimes there arises a need when a class that needs to be accessed from within the same package then default modifier is used.
For example : a third party library/jar which has a class used by other classes only within that package and it does not wants the consumers/users to use it.
