Give an example of how a static variable can be used in a class.
What will be an ideal response?
Suppose that a program needs to keep track of how many objects of a particular class have been created.
Declaring and managing a counter at the program level could be a complex task. It might be simpler to let the class itself
maintain the counter. A static int variable could be declared at the class level to be used as a counter. All of the constructors of
the class could increment the static variable. A static method would also be needed to return the value of the counter.
