Solution
Hello Please check below Changes,
1) When Color Buttons are Clicked the Only set the Color, Don't create any new point here
panel.setSelectedColor(Color.GREEN);
2)Don't Draw shape during Mouse Move. Draw Shape when Mouse is Dragged(Use Click the
mouse and Drag it) . In General any Paint Application will start Drwaing when Mouse is
Dragged on Paint Window
3)Draw line line between previous coordinate and current Coordinate. Drawing a line along
Mouse Dragged positions makes a Shape. Ovel is Different
4)Please check Below Changed Files Pasted
