/**

* Write a Person class with an instance variable, age, and a constructor that takes an integer, initialAge,

* as a parameter. The constructor must assign initialAge to age after confirming the argument passed as initialAge

* is not negative; if a negative argument is passed as initialAge the constructor should set age to 0 and print

* "Age is not valid, setting age to 0.". In addition, you must write the following instance methods:

* 1. yearPasses() should increase the age instance variable by 1.

* 2. amIOld() should perform the following conditional actions:

* - If age < 13, print "You are young.".

* - If age > 13 and age < 18, print "You are a teenager.".

* - Otherwise, print "You are old.".
