Following the examples of listing 9.8 and 9.9 in Section 9.9 in the textbook, write a program in Java to compute the following properties of automobiles: average gas mileage, lowest price, the latest model. The program must have the following: A class named Automobile, One constructor function that initializes the model year only. A method to set the gas mileage and price for the object variables. Three separate methods to compute the results (average gas mileage, lowest price, latest model) and show the outputs. The Main function will stay in another class from where the constructors and all other methods will be invoked through three objects named: sedan, minivan, and truck. Inputs are to be taken inside the Main function from the keyboard. The program will show the outputs on the screen.Sample Input (from keyboard):Enter the model year for sedan: 2012Enter the gas mileage for sedan: 35Enter the price for sedan: 20000Enter the model year for minivan: 2013Enter the gas mileage for minivan: 26Enter the price for minivan: 18000Enter the model year for truck: 2010Enter the gas mileage for truck: 21Enter the price for truck: 17000 Sample Output (on screen):Avg gas mileage: 27.33Lowest price: 17000Latest model: 2013Problem 1 (B) [5 points]: Following the example “Array of Objects” (attached to this assignment), modify the problem 1 (A) by creating an array of three objects. Rests of the functionalities, I/O, remain unchanged.Problem 2: Create a Person classFollowing the examples of listing 9.8 and 9.9 in Section 9.9 in the textbook, create a Person class that has private name and age fields (member variables). Both fields should have associated getter methods and should be set by a constructor when the object is created.Problem 2 (A) [5 points]: Following the examples of listing 9.8 and 9.10 in Section 9.10 in the textbook, create a new method (not in the Person class) that takes a Person and an age and prints a message indicating whether the person is at least that old.Sample Input:Person p1 = new Person (“Alice”, 23);checkage (p1, 17);Person p2 = new Person (“Trudy”, 47);checkage (p2, 50);Person p3 = new Person (“Jonathan”, 35);checkage (p3, 35);Sample Output:Alice is at least 17 years old!Trudy is not yet 50 years old.Jonathan is at least 35 years old!Problem 2 (B) [5 points]: Following the examples of listing 9.8 and 9.11 in Section 9.11 in the textbook, create a new method (NOT in the Person class) that searches through an array of Person objects and prints the name of the oldest one.
