Constructor problem with super keyword

Question

When I try to compile this class, I get 1 error:
C:\Program Files\Xinox Software\JCreatorV3\MyProjects\FixedDiameterCircle.java:6: cannot resolve symbol
symbol : constructor CircleGUI (int)
location: class CircleGUI
super(100);
^
1 error
class FixedDiameterCircle extends CircleGUI
     FixedDiameterCircle()
          super(100);     
     }//end FixedDiameterCircle()
public void setDiameter(int d)
}//end class FixedDiameterCircle
---------Here's the CircleGUI.java-------
import javax.swing.*; //import Swing components
import java.awt.*; //import awt components
import java.awt.event.*; //import event handlers
public class CircleGUI implements ActionListener
JTextField diameter = new JTextField(3); //text field for first name
JTextField color = new JTextField(5); //text field for last name
JButton button = new JButton("Draw"); //update button
JPanel panel = new JPanel(); //panel for frame content pane
JFrame frame = new JFrame("Draw"); //frame for window + title
public CircleGUI()
panel.add(new JLabel("Diameter")); //add a label to panel
panel.add(diameter); //add first to panel
panel.add(new JLabel("Color")); //add another label to panel
panel.add(color); //add a last to panel
button.addActionListener(this); //add a click listener to button
panel.add(button); //add button to panel
frame.setContentPane(panel); //set panel as frame's content
frame.setSize(120, 120); //set frame size (width, height)
frame.setVisible(true); //make frame visible
}//end CircleGUI()
public void actionPerformed(ActionEvent e)//executed when button is clicked
int d = Integer.parseInt(diameter.getText()); //get diameter
Circle circle; //declare Circle variable
if(color.getText().length() == 0) //if no color entered in field
{                                       //use JColorChooser below
Color rgb = JColorChooser.showDialog(frame, "Choose a Color", null);
if(rgb != null) //if Color rgb chosen
circle = new Circle(d,rgb); //instantiate Circle from Color
}//end if(color...
else
String c = color.getText(); //get color String
circle = new Circle(d,c); //instantiate Circle from String
}//end else
}//end actionPerformed()
public static void main(String[] args) //main method
CircleGUI cGUI = new CircleGUI(); //instantiate CircleGUI
}//end main()
}//end class CircleGUI
What's the problem?

Answer 1

CircleGUI does not have a constructor that takes an int. You need to either add this to CircleGui:public CircleGui(int diameter) { /* do stuff */ } or just cal super() instead of super(int). Which one is better is left as an exercise for the reader.
