Object Oriented Assignment (Need help doing these classes)

Instructions

Following classes are present in object-oriented software store:IOpenSourceSoftware InterfaceHas methods

getDeveloperCount

getPopularityScore

ICommercialSoftware InterfaceHas methods

getFeatureCount

getPrice

AbstractLinuxSoftware Abstract Class

Has method runOnAndroid

Has method - getLinuxDescription

AbstractWindowsSoftware Abstract Class

Has method runOnSurface

Has method - getWindowsDescription

MSExcel

PremiumMSExcel

ApacheSpark

LightApacheSpark

Identify all the variables and methods required for different types of softwares and use them in your Java classes. If all required variables and methods are not included, MARKS will be deducted.

Use following inheritance hierarchy.

MSExcel implements ICommercialSoftware and extends AbstractWindowsSoftware

MSExcel

getPrice method returns price multiplying feature with 5

ApacheSpark implements contracts defined in IOpenSourceSoftware and extends AbstractLinuxSoftware

getPopularityScore returns some hard coded integer

Write a specialized PremiumExcel class with following behaviors

Inherits MSExcel

getPrice method returns price multiplying feature with 10

Write a specialized LightApacheSpark class with following behaviors

Inherits ApacheSpark

Has twice the popularityScore as ApacheSpark

getLinuxDescription() of LightApacheSpark class should return (Identify variables and methods required using the following snippet):

Software Name: Light Apache Spark

Popularity Score: 200

Developer Count: 20

Time Stamp:

getWindowsDescription() of PremiumMSExcel class should return (Identify variables and methods required using the following snippet):

Software Name: Premium MSExcel

Feature Count: 10

Price: 100

Time Stamp:

Any changes to a base class should get reflected accordingly. (Example: Change in price for MSExcel changes the price of PremiumMSExcel).

Create TestSoftware.java file to test your code and put appropriate testing code for each object.

Total Possible Points: 100
