Which medication should the nurse prepare to administer as prescribed to the client In an earlier assignment you modeled an inheritance hierarchy for dog and cat pets. You can reuse the code for that hierarchy in this assignment. Write a program that prompts the user to enter data (name, weight, age) for several Dog and Cat objects and stores the objects in an array list. The program should display the attributes for each object in the list, and then calculate and display the average age of all pets in the list using a method as indicated below:public static double calculateAverage( ArrayList list ){... provide missing code ...}previous codechihuahuapublic class Chihuahua extends Dog{public void bark(){System.out.println("Bow wow");}}dogpublic class Dog{private String name;private double weight;private int age;public String getname(String n){name = n;return n;}public double getweight(double w){weight = w;return w;}public int getage(int a){age = a;return a;}public void bark(){}}import java.util.Scanner;public class DogCatTest{public static void main( String [] args){Scanner scan = new Scanner(System.in);System.out.println("Enter name");String name = scan.nextLine();System.out.println("Enter weight");double weight = scan.nextDouble();System.out.println("Enter age");int age = scan.nextInt();Dog [] dogCollection = { new Chihuahua(), new GoldenRetriever()};for( int i = 0; i < dogCollection.length; i++ )dogCollection[ i ].getname(name);System.out.println(name);for( int i = 0; i < dogCollection.length; i++ )dogCollection[ i ].getweight(weight);System.out.println(weight);for( int i = 0; i < dogCollection.length; i++ )dogCollection[ i ].getage(age);System.out.println(age);for( int i = 0; i < dogCollection.length; i++ )dogCollection[ i ].bark();System.out.println("Enter name");String cname = scan.nextLine();System.out.println("Enter weight");double cweight = scan.nextDouble();System.out.println("Enter age");int cage = scan.nextInt();Cat1 [] catCollection = { new SiameseCat(), new SiberianCat() };for( int i = 0; i < catCollection.length; i++ )catCollection[ i ].getname(cname);System.out.println(cname);for( int i = 0; i < catCollection.length; i++ )catCollection[ i ].getweight(cweight);System.out.println(cweight);for( int i = 0; i < catCollection.length; i++ )catCollection[ i ].getage(cage);System.out.println(cage);for( int i = 0; i < catCollection.length; i++ )catCollection[ i ].meow();}}public class GoldenRetriever extends Dog{public void bark(){System.out.println("Bow wow");}}public class SiameseCat extends Cat1{public void meow(){System.out.println("Meow");}}public class SiberianCat extends Cat1{public void meow(){System.out.println("Meow");}}public class Cat1{private String name;private double weight;private int age;public String getname(String n){name = n;return n;}public double getweight(double w){weight = w;return w;}public int getage(int a){age = a;return a;}public void meow(){}} In a federal system of government, power isdivided between the national government and the states.held by one person who makes all the decisions.held by a central government that makes decisions.divided equally between all state governments.
