Answer 1

Remove the line:

P1.add(f1);

This will give you a java.lang.IllegalArgumentException because you are trying to add a window to a container. It should work if you remove that line.

However, your code is totally incorrect. You are adding a JFrame to a JPanel and adding the JPanel to the JButton, it should be the opposite way around.

For example, this will work for you:

        public void Menu()
     {

             Image img = ImageIO.read(getClass().getResource("Image1.jpg"));

             JFrame f1=new JFrame("Menu");
             f1.setSize(400,200);

             JPanel P1=new JPanel();
             JButton b1=new JButton("Creamy Chocolate Cup");  
             b1.setIcon(new ImageIcon(img));

             P1.add(b1);
             f1.add(P1);
             f1.setVisible(true);
    }
