$1)$ Make a UML Class Diagram for the Ball class demonstrated in the book Listing $14\mathrm{.}3$ and $14\mathrm{.}4$

Listing $14\mathrm{.}3$

Adding an $\_\_$init$\_\_()$ method

class Ball:

def $\_\_$init$\_\_($self$,$ color, size, direction$)$:

self.color $=$ color

self.size $=$ size

self.direction $=$ direction

def bounce$($self$)$:

if self.direction $==$ "down":

self.direction $="$up$"$

myBall $=$ Ball$("$red$",$ "small", "down"$)$

print$("$I just created a ball."$)$

print$("$My ball is$",$ myBall.size$)$

print$("$My ball is$",$ myBall.color$)$

print$("$My ball's direction is $",$ myBall.direction$)$

print$("$Now I$\text{'}$m going to bounce the ball"$)$

print$()$

myBall.bounce$()$

print$("$Now the ball's direction is$",$ myBall.direction$)$

Listing $14\mathrm{.}4$

Using $\_\_$str$\_\_()$ to change how the object prints

class Ball:

def $\_\_$init$\_\_($self$,$ color, size, direction$)$:

self.color $=$ color

self.size $=$ size

self.direction $=$ direction

def $\_\_$str$\_\_($self$)$:

msg $="$Hi$,$ I$\text{'}$m a $"+$ self.size $+""+$ self.color $+"$ ball!"

return msg

myBall $=$ Ball$("$red$",$ "small", "down"$)$

print$($myBall$)$
