problem, maybe too many variables?
ere's the problem. a school assignment(extra credit) but something goes horribly wrong. i do use a DrawSquare class, which enables you to draw using move, forward, and other such commands.
Code:
public class makePolygon
{
double sidelength;
int mynumsides;
double myangle = ((mynumsides - 2) * 180.0) / mynumsides;
double r;
double R;
double perim = (mynumsides * sidelength);
makePolygon(int mynumsides, double sidelength)
{
}
double Angle(int mynumsides)
{
return myangle;
}
double getArea()
{
return ((1/2) * r * (mynumsides * sidelength));
}
double getSideLength(double sidelength)
{
return sidelength;
}
double getPerim(int mynumsides, double sidelength)
{
return (mynumsides * sidelength);
}
double calcNew(double sidelength)
{
return (Math.sqrt(4));
}
}
import apcslib.*;
import chn.util.*;
public class polygonMain
{
public static void main(String[] args)
{
double numlength;
int numsides;
double perim;
double r;
double R;
double angle;
int i;
ConsoleIO console = new ConsoleIO();
System.out.print("Number of sides: ");
numsides = console.readInt();
System.out.print("\nLength of a side: ");
numlength = console.readDouble();
makePolygon makeit = new makePolygon(numsides, numlength);
System.out.print("\nYour perimeter is: ");
perim = makeit.getPerim(numsides,numlength);
System.out.println(perim);
System.out.print("\nr = ");
r = console.readDouble();
int length = (int)numlength;
angle = makeit.Angle(numsides);
DrawingTool pen;
SketchPad paper;
paper = new SketchPad(length * 4, length * 4);
pen = new DrawingTool(paper);
pen.move(r);
pen.down();
pen.turnLeft((angle + 90));
for ( i=1; i<numsides; i++ )
{
pen.move(numlength);
pen.turnLeft(angle);
}
}
}
the output should be a regular polygon, though what happens is it moves to the point specified, then it puts the pen down(this enables it to start drawing). but instead of drawing a polygon, it draws a diagonal line that's who knows how long!! can anyone see something wrong with my code?
