Destructor methods

Objects can be created and destroyed by programs. Part of a class definition can be a method, called a destructor, that is executed when the object is to be destroyed. In Java such a method must have the identifier finalise, and an example might be:

protected void finalise(  )

  {

  System.out.println("now destroying object");

  }

This particular destructor method is not very useful, however, it illustrates that it is possible to add a destructor method to classes, so that actions can be performed by an object being destroyed.
