Parts Of the House
1. 1 arc
2. 2 different polygons (must be at least 3-sided or more than 4 sided)
3. 1 PolyLine with a minimum of 4 coordinate pairs
4. 1 rounded rectangle
5. 1 QuadCurve 2D
6. 1 CubicCurve 2D
Using Absolute coding techniques with the swing API.
7. 6 (at least) other shapes of your choice
You must use absolute coding techniques with the swing API. Your picture must be centered on any screen and shouldn't exceed 1440 by 800 (size). The size of the JFrame should not be changeable by the user. The JFrame must be titled. The Java program mist close when the JFrame is closed.
