Write the coding for the following OOP base concepts.

1. Creates vehicle class It has properties No of wheels, no of passenger, speed, keyOn which are not directly accessed but maxspeed can only directly accessed by inheritance class.

No of wheels - integer

No of passenger - integer

Keyon - Boolean

It has methods accelerate (step) , start ( ), stop ( ), break ( ), speedometer ( ) Which can be accessed anywhere but are active when keyon = true.

a. Accelerate(step) ââ?¬â?? This method increases the speed by a step value but step value is integer ââ?¬â?? 6

b. Start ()- changes the keyOn to true.

c. Stop () ââ?¬â?? changes the keyOn to false

d. Break () ââ?¬â?? this method reduces the speed by half speed become zero.

e. Speedometer ( )- show the speed of the vehicle

f. Following method are using for gets the properties of vehicle .

getNoofwheels( ),

get Noofpassenger( ),

getEnginepower( ),

getSpeed ( ),

getKeyOn( ),

getMaxspeed( ) â?¦..
