How do I use a graphics program to draw 12 strings, one for each standard color (not including white) each in its own color. Here are my two classes I started. Please, I am stuck form here.

import javax.swing.JFrame;

/**
   Shows frame with the standard color names.
*/

public class ColorNameViewer
{

   public static void main(String[] args)

   {

      JFrame frame = new JFrame();


      frame.setSize(300, 400);

      frame.setTitle("ColorNameViewer");

      frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);


      ColorNameComponent component = new ColorNameComponent();

      frame.add(component);


      frame.setVisible(true);

   }

}
 
import javax.swing.JComponent;

import java.awt.Color;

import java.awt.Graphics;

import java.awt.Graphics2D;


public class ColorNameComponent extends JComponent
{

   public void paintComponent(Graphics g)

   {
 
     Graphics2D g2 = (Graphics2D) g;

      . . .
  
 }

}

ColorNameComponent.java
import javax.swing.JComponent;

import java.awt.Color;

import java.awt.Graphics;

import java.awt.Graphics2D;

import java.awt.geom.Line2D;
import java.awt.geom.Line2D.Double;

public class ColorNameComponent extends JComponent
{

   public void paintComponent(Graphics g)

   {
   
   Color[] colors = {
   	Color.BLACK,

     for (int i = 0; i<colors.length; i++) {
     	g2.setColor(colors[i]);
   	g2.draw(new Line2D.Double(i, 0, i, 10));

This draws very small lines in the top-left corner. To change the length, position, adjust the following line of code in ColorNameComponent:

g2.draw(new Line2D.Double(i, 0, i, 10));

format: x1, y1, x2, y2
