A good answer might be:

It would be nice if different objects printed different things.

Methods can use Variables

If different instances (different objects) of the HelloObject class print different strings, then each instance must have its own data, which must be initialized. The class definition needs a constructor. Here is what a class definition usually looks like:

class ClassName
{
  Description of the variables.

  Description of the constructors.

  Description of the methods.

}

Important: An object's methods use the object's instance variables. Remember that an object has identity, state, and behavior. "Identity" means that each object has its own variables. The "state" of an object is the values held in its variables. The "behavior" of an object is its methods, which use the object's own variables.

QUESTION 15:

If each instance of HelloObject has its own message, where is that message kept?
