Question: The code below uses both instance and static methods / variables . public class Car { String name; String make; static int carCount = 0
The code below uses both instance and static methodsvariables
public class Car
String name;
String make;
static int carCount ; Static variable to track total car
count
public CarString name, String make
this.name name;
this.make make;
carCount; Increment the car count whenever a new Car is
created
Static method to reset car count
public static void setCarCountint newCount
carCount newCount;
Instance method to print car details
public void printCarDetails
System.out.printlnCar Name: name Make: make;
Static method to print total car count
public static void printCarCount
System.out.printlnTotal Cars: carCount;
public class Main
public static void mainString args
Car car new CarGeoff "Jaguar";
Car car new CarGeof "Lamborghini";
Print individual car details
carprintCarDetails;
carprintCarDetails;
Print total car count
Car.printCarCount;
Modify car count using static method
Car.setCarCount;
Car.printCarCount;
Car car new CarCharlie "Ferrari";
Car.printCarCount; Print after creating another car
Based on the code above, answer the following questions:
a What is the significance of the carCount being static? How does it behave across multiple instances
of the Car class?
b Can the static method setCarCount access instance variables like name or make? Why or why not?
c What would happen if you remove the static keyword from carCount? How would this change the
behavior of the program, especially in terms of counting cars?
d Why does the resetCarCount method have to be static? Would it make sense for this method to be an
instance method instead? Explain your reasoning.
e If you initialize carCount to a value greater than at the start, will the resetCarCount method
trigger when you create new cars? Why or why not?
f Modify the Car class to introduce a new static method resetCarCount that resets the car count to
zero, but only if the current carCount is greater than Ensure the method provides a message
indicating whether the reset was successful or not
