Question

package gui;


public class Solver {


    void solveIt(){
        CubeGui.moveThat();
    }    

}

I am trying to access method moveThat from this class, but it keeps telling me cant access non static method moveThat from a static reference. I don’t see how this is a static reference?

To expand on one of my comments left on Konrad Rudolph‘s answer…

My guess is that your CubeGui class declaration looks something like this:

public class CubeGui extends javax.swing.JFrame {
   public void moveThat() {
      // do stuff
   }
}

It should look like this (notice the static reference on the moveThat method):

public class CubeGui extends javax.swing.JFrame {
   public static void moveThat() {
      // do stuff
   }
}

Or you need the implementation of Solver to look like this:

public class Solver {
   private void solveIt() {
      new CubeGui().moveThat();
   }
}
