How do you write a program using Javafx that takes a single, positive integer, and n as a command-line argument? The program should then plot n evenly spaced points around a circle.

Answer 1

class CirclePoints

{

private int N;

private double angleTheta;

CirclePoints( int n)

{

N=n;

angleTheta = 360.0/n;

}

public double GetAngle() { return(angleTheta); }

public int GetN() { return(N); }

public static void main(String args[])

{

int N = Integer.parseInt(args[0]);

if (N>0)

{

CirclePoints myCircle = new CirclePoints(N);

double angleTheta = myCircle.GetAngle();

double angleX = angleTheta;

while (angleX <= 360)

{

double x = Math.cos(angleX*Math.PI/180);

double y = Math.sin(angleX*Math.PI/180);

System.out.println(" angle = " + angleX + " ordered pair: ("+x + "," + y+")");

angleX = angleX+angleTheta;

}

}

}

}
