Inheritance in java

Question

There were Pandavs and Kauravs. Arjun and Bheem were Pandavs. Duryodhan was a

Kaurav. Pandavs were characterized by their skills of fighting (fight ( )), obedience (obey

( )), and kindness (kind ( )). Though Bheem was little less kind but equally obedient as

Arjun. Kauravs were notorious for disobeying and cruelty. But Kauravs were fighters.

Kauravs were 100 in numbers, but one of them ‘Vikarn’ was a noble man- a good

fighter, kind and obedient. If you dive a little more in the history, you will come to know

that Pandavs and Kauravs were actually Bharatvanshi. And all bharatvanshis had been

fighters.

You are required to create a design first on paper and then write implementation on

your machine. Make abstract classes and concrete classes. Decide which methods

should be made abstract or non-abstract.

Answer 1

/*********************************************************************

Base class is Bharatvanshi

fight()

Child class Kauravs: <-- disobedient and cruel

Child class Pandavs:

fight()

obey()

kind()

protected int kindness

protected int obedience

Instances:

Pandavs Arjun, Bheem

Kaurav Duryodhan

Bheem was a little less kind but

equally obedient as Arjun

100 Kauravs, one of them Vikran was

kind and obedient
