$(10$ pts$)$ You are writing software for our recycling center truck dispatching. The center recycles paper, plastic,

and metal. All of our recyclables have a description. Paper has a type. Plastic has a number. Each metal is either

ferrous or nonferrous. And, we have trucks, each with a license plate number. Each truck has some recyclables it is

able to haul. For example, one truck can only haul PET $($#$1)$ and HDPE $($#$2)$ plastics and newspaper. Another can

only haul ferrous metals.

Draw a UML class diagram for a design that solves this problem. Be sure to indicate any aggregation and$/$or

composition.
