$1.$ Add $$swan$$ type to the simulator. $(20$ points$)$

When they make a sound, it is called that Swans are $$honking$.$

Swans can swim and fly.

a$.$ Add Swan class to info$3150\_$DuckSimulator$04$

b$.$ Add Swan class to info$3150\_$DuckSimulator$07,$ since it has another class hierarchy.

$2.$ Add $$snake$$ type to the simulator. $(40$ points$)$

Work on info$3150\_$DuckSimulator$07$ package.$$

Create Snake class that includes methods: Hiss and Swim.$$

Although snakes are not a type of duck, integrate the Snake class with the Duck class using the Bridge Pattern$$or Adapter Pattern.

In other words, Snake cannot be inherited from Duck, you need a bridge or adapter mechanism in between.

You may pick using any of these two patterns, which is easier to implement.

$3.$ Add diving behavior to the whole system. $(40$ points$)$

Work on info$3150\_$DuckSimulator$07$ package.$$

Modify TinyDuckSimulator$07.$java to list which types are diving in the water.$$

You need to define a class hierarchy for DiveBehavior, like the FlyBehavior, and use it for all Duck types.$$

Redhead ducks and snakes can dive into the water.
