Explanation / Answer

1. Encapsulation is the process of wrapping up of data and information into a single unit.we can also can it as data hiding. All the variables in a class will be hidden to the other classes in encapsulation i.e. preventing direct access to them. These can be called through the public methods in the class.

2. The data attributes will be hidden from the outside class for the security purpose which means to prvent the accidental corruption which leads to fail the program.

3. A class is like a blueprint which is used to create the objects. This consists of many things like methods,constructors etc..
A class instance is an virtual copy of the object or uinque copy of class that is representing object. A class that is in memory for execution is called as one instance
