Print one random answer out of six

Question

My code prints several answers when I need only one at a time, could you please help me print it only one at a time?

I would also like to help so that at startup a button appears on which you can click a button that will refresh the page, creating a new question, out of six anyway.

Answer 1

A call to JFrame.setSize will call the paint method. Set the size after initialization and remove it from your constructor.

 //Game Properties setTitle("WheelOP"); //setSize(750, 750); setResizable(false); setVisible(true); setBackground(Color.CYAN); setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); public static void main(String[] args){ JFrame image = new Image(); image.setSize(750,750); } 

Hope this helps.

Edit: You should also set the background color to the content panel, and not to the actual frame. And we must make it visible by doing all this. So it will look like this:

 public static void main(String[] args){ JFrame jframe = new Image(); jframe.setSize(750,750); jframe.getContentPane().setBackground(Color.CYAN); jframe.setVisible(true); }
