Java Interfaces

(a) Create an interface Vehicle which contains the methods brake() and run()

(b) Create another interface Fuel which contains the following methods:
    - fill(String type, int quantity)
    - pay(int quantity, int price)

(c) Create a subclass Car which implements both the interfaces Vehicle and Fuel
    - Here brake() method should print "Car Applies Power brake"
    - run() method should print "Car is running on 4 wheels"

(d) Similarly fill() method can print the the type and quantity of the fuel filled
    - For example: 10 Litres of Petrol

(e) pay() method can be used to print the price to be paid
    - For example: Pay Rs.640

(f) Create another subclass Bike which again implements both the interfaces Vehicle and Fuel
    - Here brake() method should print "Bike Applies hand brake"  
    - run() method should print "Bike is running on 2 wheels"

(g) Next, implement the fill() and pay() methods as explained earlier

(h) Finally create a Demo class containing the main() method to verify the results
