Create a class named Car that represents a car and holds the following fields: a String for the car model, an int for the year of manufacture, a double for the fuel efficiency in miles per gallon, and a LocalDate for the purchase date. Create a class named Garage that contains two Car objects. Create a class named Owner for a garage owner that includes the owner's name, the total number of cars owned, a String for the owner's address, and the garage info. Provide constructors for each class that accept parameters for each field, and provide get methods for each field.

Write a program that creates two Owner objects, each with two Car objects representing the cars owned by each owner. Populate the cars with details such as model, year of manufacture, fuel efficiency, and purchase date. Display the details of each owner, including the information about each car owned. Save the files as Car.java, Garage.java, Owner.java, and TestGarage.java.
