Answer 1

package javaapplication154;

import javax.swing.*;
import java.awt.*;
import java.awt.Color; //no error but not needed to write since you have included java.awt.* which gets all classes and interfaces in awt package
public class JGraphicsPanel extends JPanel
{
public JGraphicsPanel(Color color)
{
this.setBackground(color);
}
public void paint(Graphics g) //g is reference to Graphics class
{
super.paint(g); //passing g as parameter to paint()
g.setColor(new Color(0,0,0)); //passing Color object as argument to setColor() method
//Calling the below methods of Graphics class using reference 'g'
g.fillOval(10,5,40,40);
g.fillOval(60,5,40,40);
}
}

package javaapplication154;

import java.awt.Color;
import javax.swing.JFrame;
public class JavaApplication154
{
public static void main(String[] args)
{
JFrame frame=new JFrame("Using colors");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
JGraphicsPanel GraphicsPanel=new JGraphicsPanel(Color.RED);
frame.add(GraphicsPanel); //mandatory to add panel to frame
frame.setSize(400,180);
frame.setVisible(true); //sets frame visibility to true
}
}

Output
