I have an assignment to create Random Shapes by creating a method randomShape that randomly generates objects implementing the Shape interface. This is what I have so far and don't know where to go from here.

import javax.swing.JFrame;

public class RandomShapeViewer
{
	public static void main(String[] args)
	{
		JFrame frame = new JFrame();
		
		final int FRAME_WIDTH = 300;
		final int FRAME_HEIGHT = 400;
		
		frame.setSize(FRAME_WIDTH, FRAME_HEIGHT);
		frame.setTitle("RandomShapeViewer");
		frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		
		RandomShapesComponent component = new RandomShapesCOmponent();
		frame.add(component);
		
		frame.setVisible(true);
	}
}
import javax.swing.JComponent;
import java.awt.Graphics;
import java.awt.Graphics2D;
import java.awt.Shape;

public class RandomShapesCOmponent extends JComponent
{
	public void paintComponent(Graphics g)
	{
		Graphics2D g2 = (Graphics2D) g;
		RandomShapeGenerator r = 
				new RandomShapeGenerator(getWidth(), getHeight());
		
		for(int i = 1; i <= 10; i++)
			g2.draw(r.randomShape());
	}
	
	class randomShape implements Shape
	{
		
	}
}

Maybe this could be as simple as working with a few known classes that implement Shape (Rectangle, RoundRectangle2D, Ellipse2D, Polygon...), then randomly picking one of those shapes and randomly setting its parameters?
