$1.$

We$$ve given you a Person class with three instance variables $$ age, wisdom, and fitness. Those values all get initialized to different values when the constructor is called. We$$ve also provided you with mutator methods for all three variables.

Complete the hasBirthday$()$ method. This method should call the mutator methods to increase age by $1,$ increase wisdom by $5,$ and decrease fitness by $3.$

When you$$re done writing hasBirthday$()$ look at the main$()$ method to see how we$$re calling it$.$
