import class file in java [closed]

Answer 1

Be ensure that the package folder mypackage and Main.class share the parent folder.

package mypackage;
public class Child {}

I presume that the Main class is created in default package.

public class Main {
   public static void main(String []args){
         mypackage.Child child=new mypackage.Child();
   }
}

and your directory structure should be:

main-directory/
              |
              |----/mypackage/
                            Child.class
              |
              | Main.class
              | Main.java
              | Child.java

and to launch/load the Main issue following command,

java Main
