Answer 1

Basicaly you create an attribute in your class and you give it the reference to your JFrame.

 public class Myclass{

      JFrame frame;

      public MyClass(JFrame aFrame){
           this.frame = aFrame;
      }

      public void Frame_normal{


           frame.setState(Frame.NORMAL);

      }

 }

 MyClass class = new Myclass(theJFrame);
 class.Frame_normal();

Answer 2

You can do the following

1. Create the frame in the class where you want to call setState() function on it.
2. Create a getter method on that class where you are actually creating the Frame. Then use this getter to get your JFrame and call your method on it.
3. Make the JFrame public.(Not recommended)
