Some large cities (e. g., Cologne, Germany) have started a project called car-sharing to reduce the number of cars in the city and also to reduce the cost of having a car available when needed by a person. One car is partially owned by several people. The number of owners per car may vary. Typically, not more than four people own one particular car. Also, each person can own a different percentage of the car, depending on how often she uses the car. Each person might own a share of more than one car. Obviously, only one person can use the car at any particular time. Thus, a database is needed to keep track of reservations made for the car. Required:
Show the data model for the above problem including the attributes. Provide the metadata for the entities.

Write a car class having two private member variables called tank and speed. write public methods called pumpgas and gofast. the method pumpgas gets an integer for gas that must be pumped. that value needs to be added to tank (no more than 20 gallons). it must return the amount of gas that is purchased ($4 per gallon). the method gofast should increase the speed by 5 each time it is called.write a constructor for the above class that initialized both variables to zero.write a tostring to display both the tank and speed when the car is printed.modify the car class to implement the interface comparable and an interface called carinter having the public methods in carinter.write the main program to create an array of size 5 of type car. create 5 car objects having each location of the array to refer to one of the cars. test the pumpgas, gofast, equals method on the array items. write an enhanced loop to print all the car values (using a tostring written last time).write a generic method to find the minimum of four items. pass int, double, char, string and car objects to test this method.
