I want to write a code that draw this graphic



The code must be build using the following algorithms

	void drawLine(Graphics g, int x1, int y1, int x2, int y2) {

	int dx = x2 - x1;
	int dy = y2 - y1;
	putPixel(g, x1, y1);
        
	if (Math.abs(dx) > Math.abs(dy)) {
 		float m = (float) dy / (float) dx;
		float b = y1 - m*x1;
 		dx = (dx < 0) ? -1 : 1;

		while (x1 != x2) {
 			x1 += dx;
			putPixel(g, x1, Math.round(m*x1 + b));
		}
	} else	if (dy != 0) {
		float m = (float) dx / (float) dy;
		float b = x1 - m*y1;
		dy = (dy < 0) ? -1 : 1;
		while (y1 != y1) {
			y1 += dy;
			putPixel(g, Math.round(m*y1 + b), y1);
		}
	}
        
		g.setColor(Color.black);
		g.drawLine(x1 * pixelSize, y1 * pixelSize, x2 * pixelSize, y2
				* pixelSize);

	}

	void drawCircle(Graphics g,int xCenter , int yCenter , int radius){
             
	int x, y=0, r2;
        
        r2 = radius * radius;
        for (x = -radius; x <= radius; x++) {
            y = (int) (Math.sqrt(r2 - x*x) + 0.5);
            putPixel(g, xCenter + x, yCenter + y);
            putPixel(g, xCenter + x, yCenter - y);
        }    
        
		g.setColor(Color.black);
		g.drawOval(xCenter, yCenter, r2, r2);
	
        }

Honestly I don't know where to start,, any help please!

Please go through the Forum Rules -- especially the second paragraph. Don't start a new thread every time you have a follow-on question.

Moreover, it's rude to ask another question without having first replied to responses on any earlier thread. I've merged the new thread here.

I cannot edit on the first post! so I wanted to remove it (but I can't do that either!) to start new one showing the code I've tried to wrote (because you told me to try something)
Now I'm thinking of leaving the whole forum,, because nothing is work
