Get graphics

Question

I have a class called Myclass and it has a switch statment
and in the gui class which extends JFrame i want to make instances of the myclass class. which ive done
BASICALLY I HAVE A CLASS CALLED myclass AND I WANT TO PUT INSTANCES OF IT IN THE create class, AND PASS PARAMETER TO IT TO DECIDE WHAT TO DRAW. EG. myclass myclass1 = new myclass();
then say myclass1.myswitch(8) and draw this on the screen in the clas gui.
if possible pease show code I wuld would to position one instance of the left of the screen, and then the other instance 100 pixelx to the right of it and so on.
i want to pass it a parameter of 8 which will then go through to the swicth statmment as decide what to display. Now how do i display this on the screen in gui class
window.add(myclass1.myswitch(8));
This line is wrong
class Myclass extends JPanel{
public Myclass(){
super();
public void myswitch(int i){
Graphics paper = this.getGraphics();
paper.setColor(Color.black);
Graphics remove = this.getGraphics();
hit.setColor(Color.white);
switch (i){
case 1:
paper.drawLine(20,20,50,50);
hit.drawLine(70,70,50,50)
// code to draw football colour black
case 5:
// code to draw rugby ball colour black
default:
// draw trainers colour black
import java.awt.Color;
import java.awt.Dimension;
import javax.swing.JFrame;
import javax.swing.JPanel;
public class create extends JFrame{
public static void main(String []args){
Myclass myclass1 = new Myclass();
myclass1.setPreferredSize(new Dimension(100, 100));
myclass1.setBackground(Color.black);
create mycreate = new create();
mycreate.add( myclass1 );
mycreate.setVisible(true);
myclass1.mymethod(8); // trying to put this on the screen but doesnt work
}

sorry for the inconvienece i cause i shouldnt have reposted i though maybe in another section i would get more replies.
Sorry i should have been more explicit your code works perferctly boo bear.
But now i have the troble
import java.awt.*;
import javax.swing.*;
public class MainWindow extends JFrame {
     public static void main(String[] args) {
          // SwingUtilities.invokeLater ensures your GUI is created on the
          // Event Dispatch Thread.
          SwingUtilities.invokeLater(new Runnable() {
               public void run() {
                    MyPanel panel = new MyPanel();
                    panel.setPreferredSize(new Dimension(100, 100));
                    //panel.setBackground(Color.black);
                    MainWindow window = new MainWindow();
                    window.getContentPane().add(panel);
                    window.setDefaultCloseOperation(EXIT_ON_CLOSE);
                    window.pack(); // Makes window display at proper size.
                    window.setVisible(true);
                    panel.setPaintState(1);
     static class MyPanel extends JPanel {
          private int paintState;
          public MyPanel() {
               super();
          public void setPaintState(int state) {
               this.paintState = state;
               repaint(); // Tells the panel to repaint itself since state has changed
          protected void paintComponent(Graphics g) {
               super.paintComponent(g);
               g.setColor(Color.black);
               switch (paintState) {
                    case 1:
                         // code to draw football colour black
                         break;
                    case 5:
                         // code to draw rugby ball colour black
                         break;
                    default:
                         // draw trainers colour black
                         break;
}I want to set two colours one red and one yellow
paintComponent(Graphics g, Graphics hit)
super.paintComponent(g);
               g.setColor(Color.red);
super.paintComponent(hit);
hit.setColor(Color.yellow);then when i code through the switch statment i.e
switch (paintState){
case1:
g.drawLine(20,20,80,80);
hit.drawLine(10,10,40,40);
}but when i compile nothing (no lines) comes up and once i remove hit.drawLine(10,10,40,40); super.paintComponent(hit); and hit.setColor(Color.yellow);it display the orgininal line.
i seems i am unable to set two different colours
