Card for a car object: Consider a “Car” class, which simulates fuel consumption in a car. On the front side of the card, the methods that the object can execute are written. The methods for efficiency, adding gas, driving a given distance, and checking the amount of gas left in the tank that is as follows: Car myCar Car(mpg) addGas(amount) drive(distance) getGasLeft On the back side of the card, the values of the instance variables are noted down. After creating the objects, the values of the instance variables will be as follows: gasLeft milesPerGallon 0 25 Here, the initial value of “gasLeft” will be zero and the efficiency calculated in miles per gallon will be 25mpg.
