# Programming Assignment 4 - Shape Displayer
|
|
||||||
|
|
||||||
## Requirements
|
|
||||||
|
|
||||||
The user interacts with the application as follows:
|
|
||||||
|
|
||||||
- Initially, the program displays three buttons on the top of the frame and a
|
|
||||||
blank large area of a user-defined JPanel below the buttons. The buttons
|
|
||||||
display a car, a snow man, and a composite shape of your choice, respectively.
|
|
||||||
You are allowed to borrow the CarShape.java from the text book. Make sure to
|
|
||||||
acknowledge that the code is from the text book. The composite shape of your
|
|
||||||
choice should consist of at least 4 primitive shapes, but doesn't have to be
|
|
||||||
fancy.
|
|
||||||
- When the user clicks on one of the buttons, the shape displayed on the clicked
|
|
||||||
button becomes the current shape. The icon representing the current shape
|
|
||||||
should outline the shape as shown below in the sample output. When a mouse is
|
|
||||||
clicked on the user-defined JPanel, the current shape is drawn on the position
|
|
||||||
which the mouse was pressed on.
|
|
||||||
- The current shape can be changed by clicking one of the buttons.
|
|
||||||
- The application should be reusable by any CompositeShape.
|
|
||||||
- Your design should be object-oriented including ShapeDisplayer(with main
|
|
||||||
method), CarShape, SnowMan, and Your_own_shape classes. Also, it should
|
|
||||||
include interface CompositeShape.java and a concrete class ShapeIcon. You may
|
|
||||||
include more classes to your design.
