How you can modify a JPanel where is in one class, from a different class? I have a JPanel and i want to setIcon() from other class.

Thank you

public class Gui extends JFrame{

  private JPanel;


  public void setPanelIcon(...){

    jPanel.setIcon(...);

  }

}

public class Other{

  public static void main(String[] args){

    Gui gui = new Gui();

    gui.setPanelIcon(...);

  }

}

The class Other, should be main?

No, I just showed that the class containing the JPanel should get a method which allows other classes to use that method, and in the method the JPanel changes.
So even tho "Other" class doesn't know the Gui's JPanel, it can call a method of Gui, and Gui will do it itself.
