Problem Statement:

The galaxy is composed of the stars, satellite and planets etc.  In earth’s home galaxy, the solar system is comprised of sun (average star) and objects that orbits around it. Following are the 8 largest objects (planets):

1. Mercury

2. Venus

3. Earth

4. Mars

5. Jupiter

6. Saturn

7. Uranus

8. Neptune

The first four planets are called inner planets while the remaining four are outer planets. All planets revolve around the Sun and Satellites revolve around the planet.


 

The tasks you have to do are:

  1. Extract the main objects (entities) from the given scenario.
  2. Find the necessary attributes and functions that need to be associated with each object to implement the functionality mentioned above.
  3. Identify the relationships between these objects.
  4. Construct a final comprehensive Class diagram showing all objects and their relationships along with their attributes and functions.
  5. You have to use UML conventions to draw class diagram. The same has been followed in video lectures as well.

 

Note: You can use any drawing tool such as MS Visio, MS Paint or online drawing tool etc. but you have to paste your diagram in MS Word (.doc) file and submit this file on LMS. Images submitted as solution files will not be accepted.

Class :This is a programmer-defined data type, which includes local functions as well as local data. You can think of a class as a template for making many instances of the same kind (or class) of object.

 

Object An individual instance of the data structure defined by a class. You define a class once and then make many objects that belong to it. Objects are also known as instance.

What is the Difference Between a Class and an Object?

 

Classes and objects are separate but related concepts. Every object belongs to a class and every class contains one or more related objects.

So what exactly are classes and objects and what is the difference between them?

Class is static. All of the attributes of a class are fixed before, during, and after the execution of a program. The attributes of a class don't change.

The class to which an object belongs is also (usually) static. If a particular object belongs to a certain class at the time that it is created then it almost certainly will still belong to that class right up until the time that it is destroyed.

An Object on the other hand has a limited lifespan. Objects are created and eventually destroyed. Also during that lifetime, the attributes of the object may undergo significant change.

Class:

A class is the core of any modern Object Oriented Programming language Class is a blueprint of an object that contains variables for storing data and functions to performing operations on these data. 

Object: 

Objects are the basic run-time entities in an object oriented system.They may represent a person,a place or any item that the program has to handle. 

"Object is a Software bundle of related variable and methods. "

“Object is an instance of a class”

what are data member and functions 

Instance of Object

An instance is an object in memory. Basically you create object and instantiate them when you are using them.

Instance: instance means just creating a reference (copy)
