exporting non-public type through public api

[DeadSilent]

I have this code and for some reason I keep getting an error where it says "exporting non-public type through public api ".. I'm not sure why this keeps happening but it does so for getCircleInfo / drawCircle. Thanks for your help.

- Me.

package shapemaker;
 
import java.awt.*;
import javax.swing.*;
 
public class ShapeMaker {
 
    private JFrame win;
    private Container contentPane;
 
    public ShapeMaker (  ) {
        win = new JFrame("Shape Maker");
        win.setSize(400, 300);
        win.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        win.setVisible(true);
        contentPane = win.getContentPane();
        contentPane.setBackground(Color.WHITE);
    }
 
    public static void main(String[] args) {
        ShapeMaker shapeMaker = new ShapeMaker();
        shapeMaker.start();
    }
 
    public void start (  ) {
        Circle circle = new Circle (  );
        getCircleInfo(circle);
        drawCircle(circle);
    }
 
    public void getCircleInfo ( Circle circle ) {
        double radius;
        int x, y;
        radius = Double.parseDouble ( JOptionPane.showInputDialog (win, "Enter Radius") );
        circle.setRadius(radius);
        circle.setFillColor(Color.orange);
        circle.setPenColor(Color.black);
        x = Integer.parseInt( JOptionPane.showInputDialog ( win, "Enter X Cord:" ) );
        circle.setXCord(x);
        y = Integer.parseInt( JOptionPane.showInputDialog ( win, "Enter Y Cord:" ) );
        circle.setYCord(y);
    }
 
    public void drawCircle ( Circle circle ) {
        Graphics g = contentPane.getGraphics();
        circle.draw(g);
    }
}

LOL! Sorry about that, I got confused for a second.

For the exporting non-public type through public API thing, try making the method headings just void getCircleInfo ( Circle circle ) and void drawCircle ( Circle circle ). Take away the publics. Because every class in the program is part of one package, all the classes should be able to access the methods and fields from all other classes in the package even if the methods and fields have no public-private declaration. So this should work, because it gets rid of the public API, but still allows all classes access. I'm not sure exactly why all this happens, but I get the same thing with NetBeans when I try to use certain classes as parameters. I've found that this usually makes the IDE shut up. I've used other compilers/editors (i.e.) JCreator and this seems to be a problem specific to NetBeans. As for the paintComponent( ) method, chances are that it is in one of those collapsed sections of uneditable text that are generated by the design panel.

The warning is coming from your line five (5): the class Circle has no designation [i.e. public, private, etc];

Make it public and warning will disappear.

[ZRJavelin]

As to your other issues, only Classes should be capitalized; for the sake of future debugging efforts, change your variables [like Radius to 'radius'] to lower-case, so in-code references do not imply it is a reference to a static Class.

[ZRJavelin]

Based on your codes:

// Constructors
public Circle ( ) {
//setRadius(0);
this(0);
}

public Circle ( double r ) {
setRadius(r);
penColor = Color.BLACK;
fillColor = Color.WHITE;
XCord = 0;
YCord = 0;
}

and from shapemaker

public void start ( ) {
Circle circle = new Circle ( );
getCircleInfo(c ircle);
drawCircle(circ le);
}

Your constructor for a Circle requires a radius parameter; your default is 0 and no other value is passed; I contend you ARE drawing a circle, though one of radius = 0, at coords (0,0).
