Move a Rectangle object

Question

Hi guys
I'm just trying to create an applet that draws a shape such as a rectangle that will allow the user to click on the rectangle, then move the mouse and the shape will be re-drawn at the point where the mouse is released.
Any ideas where i can start, pointers greatly appreciated.

Here is the program you posted (with my corrections) which works
import java.awt.*;
import java.applet.*;
import java.awt.event.*;
public class Test extends Applet
                            implements MouseListener
    private Color color = Color.black;
        int x1, y1, x2, y2 = 0;
int width, height = 0;
  int startX, startY = 0;
boolean drawObject = false;
     boolean moveObject = false;
     Rectangle myRectangle = new Rectangle(startX,startY,width,height);
    public void init()
        setBackground(Color.gray);
        addMouseListener(this);
        int i = 5;
    public void paint(Graphics g)
          //recover Graphics2D
            Graphics2D g2 = (Graphics2D)g;
          g2.setColor(color);
             if(drawObject){
                 //create Rectangle Object
                        myRectangle = new Rectangle(startX,startY,width,height);
                      g2.draw(myRectangle);}
          else if (moveObject){
                   g2.drawString("MOVE", 100,100); //just testing here
                     myRectangle.setLocation(x2,y2);}
    //--> Start of section dealing with Mouse Events
    public void mouseClicked(MouseEvent e)
    public void mouseEntered(MouseEvent e)
    public void mouseExited(MouseEvent e)
    public void mousePressed(MouseEvent e)
           x1 = e.getX();
          y1 = e.getY();
          //Check to see if mouse is pressed in the current rectangle.
            if(myRectangle.contains(x1,y1))
                       //move the object instead of moving it
                  drawObject = false;
                     moveObject = true;
               else
                       //draw the object, don't move
                   drawObject = true;
                      moveObject = false;
    public void mouseReleased(MouseEvent e)
               //get the positions of where the mouse was released
             x2 = e.getX();
          y2 = e.getY();
          if (x1 != x2 && y1 != y2){
          //maths to work out where to draw the object
            if(x1 < x2 && y1 < y2){//1
                      startX = x1;
                    startY = y1;
                    height = y2 - y1;
                       width = x2 - x1;}
               else if (x1 > x2 && y1 > y2){//2
                        startX = x2;
                    startY = y2;
                    height = y1 - y2;
                       width = x1 - x2;}
               else if (x1 > x2 && y1 < y2){//3
                        startX = x2;
                    startY = y1;
                    height = y2 - y1;
                       width = x1 - x2;
               else if (x1 < x2 && y1 > y2){//4
                        startX = x1;
                    startY = y2;
                    height = y1 - y2;
                       width = x2 - x1;}
               } repaint();
}I.e. User can draw a rectangle; clicking inside it causes string MOVE to appear at point 100,100. If you want to redraw rectangle at point where mouse has been clicked, try to think about it a bit and post your code if it wont work. Do not ask to write it for you.
