Drawing a shape in java???

[ddmeightball]

Im supposed to Draw a shape or place an image on the screen and invite the user to click on it. When the user clicks on the shape, move it to a new random location. It has to be when the user clicks on the image/shape, not around it so I need to get the coordinates for the mouseclick event and compare them with location.x and location.y in an if-else statement.

If the mouse coordinates == location.x and location.y then move image randomly. If not, do nothing.

What I need to know how to do is draw a shape, like a square, then get the coordinates of the mouse click. Can anyone help?

fill(new Rectangle(x, y, w, h));


that's how to draw a rectangle.


public void mouseClicked(MouseEvent me)
{
int x, y;
x = me.getX();
y = me.getY();
}


and that will get the coordinates of a mouse click.



I wish I could help you a little more, but my compiler has something wrong with it, and goes crazy when I do anything with graphics.

I know!! I was just playing around with you!

[ddmeightball]

I figured out the MouseHandler error. That was the name of the class that I was calling to decide whether or not the square was clicked. I changed it to MouseAdapter and it worked just fine now. Thanks everyone for your help.
