Question

1. Explain the differences between a class and an object.

2. Explain what it means to instantiate an object.

3 .Explain the advantages of using objects over arrays and collections in terms of encapsulation

Answer 1

1) Difference between a class and an object are :-

Class is a template or idea from which objects are created. It has all the functions and variable with labels which are used by the object. And, whereas we know object is an instance of a class. One can say class is a logical entity whereas object is a physical entity

2) Instantiate an object means construction of an object which a group of properties defined by the class and it's constructor and functions. Initialize with the given and default values. Simple words to create a instance of an object

3)Main advantage of object over arrays and collections in terms of encapsulation is that through object one can encapsulate different items at once ; not necessarily same type of items.
