Question

I am writing a program to monitor animals and habitats in a zoo, reading from 2 different .txt files. The animals portion of my code is working perfectly, but when I try to execute the habitats portion, I get errors. Below is both my code and recieved errors:

import java.util.Scanner;
import java.io.FileNotFoundException;

public class ZooMonitor {
static fileread fr = new fileread();

private static Scanner scnr = new Scanner(System.in);
public static void main(String[] args)throws FileNotFoundException {

while(true){
    int choice = menu();
    if(choice == 1){
   
    // Select animal
    int animal = animal_select();
    String Type = "";
    String Name = "";

    switch (animal){
    case 1:
    Name = "Animal - Lion";
    break;
    case 2:
    Name = "Animal - Tiger";
    break;
    case 3:
    Name = "Animal - Bear";
    break;
    case 4:
    Name = "Animal - Giraffe";
    break;
    case 5:
    }
    //read requested information from file

    fileread.read_animal(Name);
    }
    else if(choice == 2){

        //select the habitat

        int animal = habitat_select();
        String Type = "";
        String Name = "";

        switch (animal){
        case 1:
        Name = "Habitat - Penguin";
        break;
        case 2:
        Name = "Habitat - Bird";
        break;
        case 3:
        Name = "Habitat - Aquarium";
        break;
        case 4:
     }

//read requested information from file

        fileread.read_habitat(Name);
        }
    else{
        System.out.println("Thank You!");
        System.exit(0);
     }  
    }
}

private static int habitat_select(){
   
    //Display habitat options

    System.out.println("1.Habitat - Penguin ");
    System.out.println("2.Habitat - Bird");
    System.out.println("3.Habitat - Aquarium");
    System.out.println("Enter your choice, 1-3");
    int choice = scnr.nextInt();
   
    return choice;
}

private static int animal_select(){
   
    //Display animal options

    System.out.println("1.Animal - Lion");
    System.out.println("2.Animal - Tiger");
    System.out.println("3.Animal - Bear");
    System.out.println("4.Animal - Giraffe");
    System.out.println("Enter your choice, 1-4");
    int choice = scnr.nextInt();

    return choice;
}
private static int menu(){
   
    //Main menu

    System.out.println("1.Monitor animals");
    System.out.println("2.Monitor habitats");
    System.out.println("3.Exit");
    int choice = scnr.nextInt();

    return choice;
}

}

//Second .java file

import java.io.File;
import java.io.FileNotFoundException;
import java.util.Scanner;
import javax.swing.JOptionPane;

public class fileread {
    private static Scanner fileread;

    // constructor
    public fileread(){
    fileread = null;
}
public static void read_animal(String Name) throws FileNotFoundException{
    //read from the animals.txt file
    fileread = new Scanner (new File("C:\Users\Debbie and Drew\Desktop\animals.txt"));
    boolean cont = true;
    String Type = "";

    //read the file until match found
    while(fileread.hasNextLine() &&cont){
        Type=fileread.nextLine();
    if(Type.equals(Name))
        cont = false;
     }

    //read file data
    String animal_name = fileread.nextLine();
    String animal_age = fileread.nextLine();
    String animal_health = fileread.nextLine();
    String animal_feed = fileread.nextLine();
   
    //prints information
    System.out.println(animal_name);
    System.out.println(animal_age);
   
    //if warning present, display
    if(animal_health.contains("*****")) {
        JOptionPane.showMessageDialog(null, animal_health.substring(5,animal_health.length()), "Warning : " + Type, JOptionPane.INFORMATION_MESSAGE);
    }
    else {
        System.out.println(animal_health);
    }

    if(animal_feed.contains("*****")) {
        JOptionPane.showMessageDialog(null, animal_feed.substring(5,animal_feed.length()), "Warning : " + Type, JOptionPane.INFORMATION_MESSAGE);
    }
    else {
        System.out.println(animal_feed);
    }
    }
public static void read_habitat(String Name) throws FileNotFoundException{
    //read from the habitats.txt file
    fileread = new Scanner (new File("C:\Users\Debbie and Drew\Desktop\habitats.txt"));
    boolean cont = true;
    String Type = "";

    //read file until match found
    while(fileread.hasNextLine() &&cont){
        Type = fileread.nextLine();
    if(Type.equals(Name))
        cont=false;
    }

    //read information
    String temperature = fileread.nextLine();
    String food = fileread.nextLine();
    String cleanliness = fileread.nextLine();

    //if warning present, display
    if(temperature.contains("*****")) {
        JOptionPane.showMessageDialog(null, temperature.substring(5,temperature.length()), "Warning : " + Type, JOptionPane.INFORMATION_MESSAGE);
    }
    else {
        System.out.println(temperature);
    }

    if(food.contains("*****")) {
        JOptionPane.showMessageDialog(null, food.substring(5,food.length()), "Warning : " + Type, JOptionPane.INFORMATION_MESSAGE);
    }
    else {
        System.out.println(food);
    }

    if(cleanliness.contains("*****")) {
        JOptionPane.showMessageDialog(null, cleanliness.substring(5,cleanliness.length()), "Warning : " + Type, JOptionPane.INFORMATION_MESSAGE);
    }
    else {
        System.out.println(cleanliness);
    }
}

}    This results in the following:

Exception in thread "main" java.util.NoSuchElementException: No line found
at java.util.Scanner.nextLine(Scanner.java:1540)
at fileread.read_habitat(fileread.java:65)
at ZooMonitor.main(ZooMonitor.java:61)
