Question

Below I have my 3 files. I am trying to make a dog array that aggerates with the human array. I want the users to be able to name the dogs and display the dog array but it isn't working.

//Main File

import java.util.*;
import java.util.Scanner;
public class Main
{
   public static void main(String[] args)
   {
   System.out.print("There are 5 humans.\n");
   array();
  
   }
   public static String[] array()
   {
  
   //Let the user enter the names of the humans
   String[] humans= new String[5];
   Scanner input = new Scanner(System.in);
   System.out.print("Enter the " + humans.length + " names: ");
   for (int i = 0; i < humans.length; i++)
   {
   humans[i] = input.nextLine();
   }
  

   for(int i=0;i<humans.length; i++)
   {
   System.out.print(humans[i]+" ");
   }
   return humans;
   }
}

//Human file

import java.util.*;
import java.util.Scanner;

public class Human
{
Dog [] dogs;
   public static void main(String[] args)
   {

   }
   public Human()
   {
   int numDogs = Dog.random();
   dogs = new Dog[numDogs];
  
   for(int i=0; i<dogs.length; i++)
   {
   dogs[i] = new Dog();
   }
  
   for(int i=0;i<dogs.length; i++)
   {
   System.out.print(dogs[i]+" ");
   }
     
   }   
}

//Dog file

import java.util.*;
import java.util.Scanner;

public class Dog
{
   public static void main(String[] args)
   {
  
   }
   public static int random()
   {
   int num = (int) (Math.random());
   String[] dogs = new String[num];
   return num;
   }
   public Dog()
   {

  
   }
}

import java.util.*;

public class Main {

    public static void main(String[] args) {
        System.out.print("There are 5 humans.\n");
        
        // Let the user enter the names of the humans
        Human[] humans = new Human[5];
        Scanner input = new Scanner(System.in);
        System.out.print("Enter the " + humans.length + " names: ");
        for (int i = 0; i < humans.length; i++) {
            humans[i] = new Human(input.nextLine());
        }

        for (int i = 0; i < humans.length; i++) {
            humans[i].print();
        }
        input.close();
    }
}

class Human {
    String name;
    Dog[] dogs;

    public Human(String name) {
        this.name = name;
        int numDogs = (int) (1 + 5 * Math.random());
        dogs = new Dog[numDogs];

        for (int i = 0; i < dogs.length; i++) {
            dogs[i] = new Dog();
        }
    }

    public void print() {
        System.out.println("Name: " + name);
        
        System.out.print("Dogs: ");
        for (int i = 0; i < dogs.length; i++) {
            System.out.print(dogs[i].getName() + " ");
        }
        System.out.println();
    }
}

class Dog {
    String name;
    
    Dog() {
        String names[] = {"Ace", "Apollo", "Bailey", "Bandit", "Baxter", "Bear", "Beau", "Benji",
                "Benny", "Bentley", "Blue", "Bo", "Boomer", "Brady", "Brody", "Bruno", "Brutus", "Bubba",
                "Buddy", "Buster", "Cash", "Champ", "Chance", "Charlie", "Chase", "Chester", "Chico"};
        name = names[(int) (Math.random() * names.length)];
    }

    public String getName() {
        return name;
    }
    
}
