What is Encapsulation?

Encapsulation - is the ability of an object to hide its data and methods from the rest of the world. It is one of the fundamental principles of OOPs.

Say we create a class, named Calculations. This class may contain a few members in the form of properties, events, fields or methods. Once the class is created, we may instantiate the class by creating an object out of it. The object acts as an instance of this class, the members of the class are not exposed to the outer world directly, rather, they are encapsulated by the class.

Example:
Public class Calculations
{
  private void fnMultiply(int x, int y)
  {
  return x * y;
  }
}
...
...
Calculations obj;
int Result;
Result = obj.fnMultiply(5,10);
