Can I make a drawing program by Java?

I want to make a java program that can draw some graphics like rectangle, circle, polygon. When we draw , we can resize or move it after. How can I do this.. Java can do this kind of program ? Could u tell me the website that teach about this ?

I want to make it and use it in the internet(applet)
Thank you

yes, its possible,

this is a little examble to draw:

Code:

---

import java.swing.*;
import java.awt.*;
public class Test extends JFrame{
 public Test(){
  super("Test");
  setSize(400, 400);
  setDefaultCloseOperation(EXIT_ON_CLOSE);
 }
 public static void main(String args[]){
  new Test();
 }
 public void paint(Graphics g){
  super.paint(g);
  g.drawRect(0, 0, 50, 50);
  g.fillOval(100, 100, 200, 200);
 }
}

you can use MouseMotionListener and variables to make the drag effect...

take a look in the Java API specification on the classe Graphics and the interface MouseMotionListener

You can use the attached source code as you wish. You can modify it, use it as a guide or pull out your hair as you try to understand it.

See: 2D Graphics

Moveover, suppose that the user drawed 2 rectangles, after that he wants to modify it. he's clicking one of rectangle and resize its or delete its.
