Try this challenge to make sure you understand the difference between local and instance variables, which is a common point of confusion for beginners to programming.
instance variables are defined at instance level and can have a different value for each instance. static variables are defined at class level and share one value among the instances. For example, if you have a class Person with instance variable name and static variable numberOfPeople, you can...
