I was wondering if anyone could help me out on my wheel project. I am kind of new at Java and needed some help. This project is a wheel and has to have 5 spokes. So far I have.....

class Spoke { }

class Wheel
{
Spoke[] spokes = new Spoke[5];
}

any help is accepted. Thanks again.

well, you have a start. you have a spoke class, and a wheel class. you have an array to hold your spokes. However, you have not yet created any spokes.

declaring an array is like saying "i want a carton that can hold 5 eggs", and you get a carton. There are, however, no eggs in it.

do you know how to create the spokes and put it into the array?

^^Thanks. I added what you pasted, but it's saying "Return Type Method Is Missing". It's saying that at Wheel(). I know wheel is a method, but not sure why that error is coming up.

import java.applet.*;

public class Wheel extends Applet

Wheel is not void, it's the constructor for the class Wheel (the method has the same name as the class).

Anyway I have no idea what you're trying to do and I think neither do you. What exactly are you trying? an applet with a draw of a wheel?

I got another question. I was wondering do they have a method for a Circle. I see one for Polygon, Arc, Line, Rec, Oval, Round Rect....anything for a Circle?

Sure! An oval has two different radios and a circle as only one radio, so put the same value for the two parameters that defines the radios and you'll get a circle

So far I got:

import java.applet.Applet;
import java.awt.Graphics;

import javax.swing.JFrame;

public class DrawOval extends Applet
{
public void paint (Graphics g)
{
g.drawOval(10, 50, 200,
getSize() .height - 384);
getSize() .getWidth();

Somewhat correct???
