Chapter 5, Problem 2OC
Program Plan Intro
Radio-Frequency Identification used for monitoring the production and distribution process of marijuana:
- The Radio-Frequency Identification (RFID) technology uses bar codes to closely watching even the plant’s trimming because though customers only smoke the marijuana flower so called waste weight is just as important to the state MMED.
- The use of Radio-Frequency Identification tags for every single individual plant, regulators, every plant and batch package are able to track the plants from “bud to blunt” and determine when plants go missing.

- Java Graphics (Bonus In this lab, we'll be practicing what we learned about GUIs, and Mouse events. You will need to implement the following: A GUI with a drawing panel. We can click in this panel, and you will capture those clicks as a Point (see java.awt.Point) in a PointCollection class (you need to build this). The points need to be represented by circles. Below the drawing panel, you will need 5 buttons: O о о ○ An input button to register your mouse to the drawing panel. A show button to paint the points in your collection on the drawing panel. A button to shift all the points to the left by 50 pixels. The x position of the points is not allowed to go below zero. Another button to shift all the points to the right 50 pixels.
