Small Introduction about Class and Object

1)What is class?

>Class is plan of the software object our computer  is going to create.

>Class is a logical representation(imaginary representation)

>Class is not a physical representation

2)What is an object?

>Physical  representation of a class(instance of a class)

>Software Objects are occupying space in the computer memory.

>Anything that is occupying space is called physical representation.

>To represent realtime object in computers we  create software objects.

>Software Object  is collection of variables and methods.

3)What is the difference between a class and an object?

>Logical Representation versus physical representation

>Imagination versus Actual(real)

4)What are the differences between objects?

>When we create a software object it occupies space in the computer memory.

>This space is identified using a unique identification number called memory address.

>The space in the computer called memory location.

>Whenever  we create two software objects  these occupies different memory locations.

>Whenever we compare these software objects their memory locations will be compared.

>Because these memory locations are different(memory addresses are different) any two software objects in the computer  are not same.

Note:

For a single class we can create any number of software objects depending on the availability of computer memory.
