On-screen circumference

Objective

Create a Java program that generates the drawing of a circle on the screen, dividing it into 360 equidistant points. Use the provided formula below to calculate radians. To position each point on the circle, you can use the angle value and calculate the corresponding x and y coordinates to draw the circle.

The necessary formula is:

radians = angle * PI / 180

Solution

CircleOnScreen.java

public class CircleOnScreen {
    public static void main(String[] args) {
        double x, y;
        double radius;

        for (int i = 0; i < 360; i += 5) {
            radius = i * Math.PI / 180.0;

            x = 35 + 8 * Math.cos(radius);
            y = 10 + 8 * Math.sin(radius);

            // Round the coordinates to integers
            int posX = (int) Math.round(x);
            int posY = (int) Math.round(y);

            for (int j = 1; j < posX; j++) {
                System.out.print(" ");
            }

            for (int j = posX; j <= posX; j++) {
                for (int k = 1; k < posY; k++) {
                    System.out.print(" ");
                }
                System.out.println("X");
            }
        }
    }
}
