Java Programming

Hi all,

I'm new to this forum. This is my first post. I'm working on an assignment for my Intro to Java class and need some help. I wrote the program already, and I'm fairly sure it should work, but it won't show the picture when I try to run it.

The program is supposed to draw concentric octogons, each larger than the previous. This is due at midnight tonight, so any help is needed ASAP.

Thanks a lot. Here is my code.


import java.awt.Color;

public class filename
{
public static void main(String[] args)
{

Picture pict = new Picture (640, 480);
Turtle turtle1 = new Turtle(pict);

int count;
int length;

//center the turtle
turtle1.penUp();
turtle1.turn(-90);
turtle1.forward(25);
turtle1.turn(-90);
turtle1.forward(20);
turtle1.turn(180);
turtle1.penDown();

length = 10;

count = 0;
while (count < 10);

{
turtle1.drawOctogonWithColor ( (length) , Color.red );
turtle1.penUp();
turtle1.turn(-90);
turtle1.forward(5);
turtle1.turn (-90);
turtle1.forward(5);
turtle1.turn(180);
turtle1.penDown();

count++;
length = length + 5;
}


pict.show();

}
}





Also, the method for drawOctogonWithColor is defined in another file. Here is the code for that method:



public void drawOctogonWithColor (int length, Color colorParam)
{
int loopCount;

this.setPenColor (colorParam);

loopCount = 0;
while (loopCount < 8)
{
this.forward(length);
this.turn (45);
loopCount++;
}
}
