$1-$Create a constructor in the Dog class that takes two input parameters and uses those parameters to initialize the instance variables.

$2-$ In the main method inside the driver class, declare a variable of type Dog $($call it myDog$)$ and instantiate it with values of your choice.

$3-$In the main method inside the driver class, declare a variable of type Dog $($call it yourDog$).$ Instantiate it with appropriate values so that it represents a $2$ year old bulldog.

$4-$Add a getter for all of the variables of the dog class. Add a setter for all of the variables of the dog class.

$5-$When should your class have a getter for a variable? When should your class have a setter for a variable?

$6-$ Create a toString$()$ method for your Dog class. What sentence will you use to describe the dog?

$7-$ Add a static counter to the dog class. Create a variable to hold the dog$$s id$.$

Update the constructor$($s$)$ to use the static variable to assign a unique id to every dog that is created.

$8-$ Add an equals$()$ method to the dog class. Two dogs should be considered equal if they have the same id$.$

$9-$ Suppose that x $,$ y and z are all Double objects. Describe all the boxing and unboxing that occurs in the assignment z $=$ x $+$ y
