random color fill

Hi I am trying to create a randomly color filled oval but the outcome is a black filled oval this is the code: package assignment2;

import java.awt.Color; import java.awt.Graphics; import java.util.Random; import javax.swing.JPanel;

public class RandomDrawPanel extends JPanel {

@Override
protected void paintComponent(Graphics g) {

    int x = 5;
    int y = 7;
    Random rcolor = new Random();
    int r = rcolor.nextInt(255);
    int g1 = rcolor.nextInt(1);
    int b = rcolor.nextInt(250);

    g.drawOval(x, y, 200, 200);
    g.fillOval(x, y, 200, 200);
    Color randomColor = new Color(r, g1, b);

}

}

and for the output:

package assignment2;

import javax.swing.JFrame;

public class RandomDrawing {

/**
 * @param args
 */
public static void main(String[] args) {
    RandomDrawing shape = new RandomDrawing();
    shape.go();

}

private void go() {
    // TODO Auto-generated method stub
    JFrame frame = new JFrame();
    RandomDrawPanel oval = new RandomDrawPanel();
    frame.getContentPane().add(oval);
    /*try {
        Thread.sleep(2000);
    } catch (InterruptedException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
        System.out.println(e);
    }*/
    frame.setSize(500,500); 
    frame.setVisible(true);
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}

}
