Sphere by Lines

This a trivial graphics program i made. I draw a sphere using loop to change the degree of the rotation theta.

java code

// LineCircle.java
import java.awt.Color;
import java.awt.Graphics;
import javax.swing.JFrame;

/**
*
 
*/
public class LineCircle extends JFrame{
    
    /** Creates a new instance of LineCircle */
          
    private int r=200;
    private float theta;
    private int width=500;
    private int height=500;
    private int x=0;
    private int y=0;
    public LineCircle() {
         setTitle("Codemiles");
         setSize(width,height);
         
    }
    public void paint(Graphics g) {
        g.fillRect(0,0,500,500);
        g.setColor(Color.RED);
        int drawX=0;
        int drawY=0;
        int color=0;
        while(theta<360)
        {
             g.setColor(new Color(255-color,10+color,color));
           drawX=(x+(int)(r*Math.cos(theta)));
            drawY=(y+(int)(r*Math.sin(theta)));
            g.drawLine(0+250,250-0,drawX+250,250-drawY);
            theta+=0.5;
            if(theta%2==0)
            color++;
        }
    }
    
    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {
        // TODO code application logic here
        LineCircle LC=new LineCircle();
        LC.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        LC.setVisible(true);
    }

    

}
