compile time error diba? The solution is to catch the exception.

 if (e.getActionCommand().equals("BasketBall Price"))
    {
      Basketball_Price bb=new Basketball_Price();
      try 
       {
         bb.printbb(); 
       }
       catch(IOException exception)
       {
         //do something here...
       } 
    
     }

  public void actionPerformed(ActionEvent e) throws IOException {
    Container contentPane = getContentPane();
    
    if (e.getActionCommand().equals("Exit")) {
      System.exit(0);
    }
     
    if (e.getActionCommand().equals("BasketBall Price")) {
      Basketball_Price bb=new Basketball_Price();
