Define the term black box, and explain why it is an important concept in object-oriented analysis. Can you think of other black boxes that you use in everyday life?
What will be an ideal response?
An object can be viewed as a black box, because a message to the object triggers changes within the object without specifying how the changes must be carried out. One advantage to using a black box approach is that you do not need to think about how the object performs a task, as long as it does so properly.
