Question

I need help writing this java program, here is what it wants me too code.

Write a JavaFX application that draws a circle using a rubberbanding technique. The circle size is determined by a mouse drag. Use the initial mouse press location as the fixed center point of the circle. Compute the distance between the current location of the mouse pointer and the center point to determine the current radius of the circle.

import java.applet.Applet; import java.awt.Graphics; import java.util.Random; import java.awt.Color; import java.awt.event.MouseMotionListener; import java.awt.event.MouseListener; import java.awt.event.*; public class Rubberband extends Applet implements MouseMotionListener , MouseListener { int status; int x1=0; int x2=0; int y1=0; int y2=0; public void init() { addMouseListener(this); addMouseMotionListener(this); }     public void mouseMoved(MouseEvent e){} public void mouseClicked(MouseEvent e) { status=1; x1=e.getX(); y1=e.getY(); } public void mouseDragged(MouseEvent e) { x2=e.getX(); y2=e.getY(); repaint(); } public void mouseReleased(MouseEvent e){} public void mousePressed(MouseEvent e){} public void mouseEntered(MouseEvent e){} public void mouseExited(MouseEvent e){} // write paint() method to draw on applet window public void paint(Graphics g) { while(status==1) { g.setColor(Color.red); int dis=(int)Math. sqrt((x2-x1)*(x2-x1) + (y2-y1)*(y2-y1)); g.drawOval(x1-dis,y1-dis,2*dis,2*dis); } } }
