I'm getting the following error in my code:
Implicit super constructor GLabel() is undefined for default constructor. Must define an explicit constructor
My parent class "GLabel" is contained in an external jar. I can open the source file, but I can't make edits to it. So I decided to extend GLabel to create the functionality I want.
As you can see "GLabel" class does not have an empty constructor. I'm assuming this is what is causing the issue? How do I fix this?
Child Class
import acm.graphics.GLabel;
public class BreakoutLabels extends GLabel{
// no code inside
}
Parent Class
public class GLabel extends GObject {
public static final Font DEFAULT_FONT = new Font("Default", 0, 12);
private String label;
private Font labelFont;
public GLabel(String str) {
this(str, 0.0D, 0.0D);
}
public GLabel(String str, double x, double y) {
label = str;
setFont(DEFAULT_FONT);
setLocation(x, y);
}
}
If GLabel
doesn't have a default (empty-args) constructor, then your constructors for your derived class have to call one of the declared constructors for GLabel
. However GLabel
is defined means that a default constructor makes no sense, and you'll have to provide suitable arguments.
