This part of the assignment is meant to give you some practice with the DrawingPanel and Graphics classes. Complete the drawingOne() method in the ScintillationGrid. java program. Do not alter the method signature for the drawingOne() method in any way. You can either produce a specific output or you can design your own output. If you want to design your own, it must meet the following criteria:The DrawingPanel's size must be at least 400 x 200 pixels. It can be larger than this. You must draw at least one line, one rectangle, and one oval that are visible on the screen. You must use at least three different visible colors in your figure. The picture shall not include hateful, offensive, or otherwise inappropriate images. Do not animate your drawings. We won't see any animations when we run our grading scripts, so do not attempt to add animation.
