Explain why a class might provide a set method and a get method for an instance variable.
What will be an ideal response?
An instance variable is typically declared private in a class so that only the methods of the class in which the instance variable is declared can manipulate it. This prevents the variable from being modified accidentally by a class in another part of the pro- gram. In some cases, it may be necessary for an application to modify the private data. For example, the owner of a bank account should be able to deposit or withdraw funds and check the account’s balance. A class’s designer can provide public set and get methods that enable an application to specify the value for, or retrieve the value of, a particular object’s private instance variable.
