package ( core java )

step 1:
           path ="D:\javaprogram"
         

           code  under directory "D:\javaprogram" :

           package javaprogram;
           public class p1
          {
                   public void print()
                   {
                                    System.out.println("asdfg");
                   }
           }
             

step 2: compile:
     

                         C:\Users\user>d:

                         D:\>cd javaprogram

                         D:\javaprogram>javac p1.java

                        D:\javaprogram>cd ..

                       D:\>


step4 :  create p2.java under directory "d:"

step5  (optional) : for checking , if package is created or not ( if main() is present in p1 class)
                             

                          D:\>java javaprogram.p1 ( if main() is not present , it will get an error)




step 6: code of p2.java

            import javaprogram.p1;
