in JAVA, implement a class Car with the following properties. A car has three instance variables: a fuel efficiency measured in miles/gallon, a tank value that specifies the total gallons the tank will hold, and a certain amount of fuel in the gas tank. The efficiency and tank values are to be set by parameters in the constructor, and the initial fuel level should be set to 0 by the constructor. Supply a method drive that simulates driving the car for a certain distance, reducing the fuel level in the gas tank, and methods getFuelLevel, that returns the current fuel level, fillTank, which returns the number of gallons to fill the tank, and lastly, setFuel(int n) which will add n gallons of gas to the tank. Write a test class that demonstrates each of your methods.
