Answer to Question 2
Objects do not create themselves: each object must be instantiated by another object. In most object-oriented languages, an object may implement constructor methods that allows the entity that instantiates the object to provide it with information that it needs from inception to provide any service. Constructors are like other methods and can be even overloaded, but they have the same name as the class and cannot be accessed after the object has been instantiated.
Destruction of objects often does not require explicit actions: when other objects no longer refer to an object, it is automatically destroyed by the runtime environment. Sometimes, however, you need to destroy objects explicitly.
