Hi Sandeep,

Defining attributes of a class in the private visibility section is called “Information Hiding” or Encapsulation.

<u><b>Advantage</b></u>

If the attributes are defined as public, the risk would be too large since a user might forget to supply value to attribute or specify an inconsistent value to an attribute.

So the attributes are defined as private so that user cannot directly access them but through methods which are defined in the public section. A strict syntax check governs method calls to check that all obligatory parameters are transferred. Methods can also perform a consistency check and raise an exception if an error occurs.

<u><b>Disadvantage</b></u>

Assigning values to attributes through methods instead of direct assignment

(for public attributes) require slightly more runtime.

Award points if found useful.
