Object Creation and Destruction

To create an object of a particular class use the new operator. For example, now that there is a constructor for the Box class you can make specific instances or discrete copies of a box by using the assignment operator and the new memory allocation operator as in:

Box box_1=new Box(3,4,5);

Note: Once a class has been specified, a datatype exists with the same name.
You do not need to destroy or remove an object when it is no longer needed. Java automatically flags unused objects and applies garbage collection when appropriate. However you may occasionally need to use the finalize() method to insure that a non-Java resource such as a file handle or a window font character is released first. The general form is:

void finalize()
{
  //cleanup code goes here
  super.finalize() //parent too!
}
