Having defined the RatingPanel
constructor,
you now proceed to the setters and getters required by the
RatingPanelInterface
interface.
The getters are straightforward; each returns a value:
public int getValue1() {return value1;}
Elementary setters also are straightforward; each assigns an instance variable and updates a text field:
public void setValue1(int v) { value1 = v; field1.setText(String.valueOf(value1)); }
