In Java you can only import class Names  or static methods fields   To import class use  import full package name of SomeClass    We can also import static methods fields in Java and this is how to import  import static full package nameOfClass staticMethod  import static full package nameOfClass staticField

You don t import methods in Java  only types   import Dan Vik  class Kab       public static void main String args                  Vik Sam   new Vik            Sam disp              The exception is so-called  static imports   which let you import class  static  methods from other types

For the second class file  add  package Dan   like the first one  so as to make sure they are in the same package  modify  import Dan Vik disp   to be  import Dan Vik

Here is the right way to do imports in Java   import Dan Vik  class Kab   public static void main String args          Vik Sam   new Vik        Sam disp          You don t import methods in java  There is an advanced usage of static imports but basically you just import packages and classes  If the function you are importing is a static function you can do a static import  but I don t think you are looking for static imports here
