Question

import static com.example.hello.Tools.*;
public class MAINCLASS{
   public void run(){
      runtools(); // this works
   }
   private class People{
      public void runpeople(){
          runtools(); // this does not work.
      }
   } 
}

Inside Tools…

Edit: When I roll over runtools() in People.runpeople()…I get this:

The method runtools() is undefined for the type MAINCLASS.People

public class Tools {
    public void runtools() {
     ....
    }
}

Does anyone know why?

Answer 1

You need to declare Tools#runtools() static to be able to import static it.

public class Tools {
    public static void runtools() {
        // ...
    }
}

Either that, or instantiate Tools and then call runtools() on it.

new Tools().runtools();
