Explain the purpose of an instance variable.
What will be an ideal response?
A class provides an instance variable (or several instance variables) when each object of the class must maintain information separately from all other objects of the class. For example, a class called Account that represents a bank account provides an in- stance variable to represent the balance of the account. Each Account object main- tains its own balance but does not know the balances of the bank’s other accounts.
