The objectives of this lab exercise are to introduce you to NetBeans IDE and refresh your knowledge about java classes.  You will be developing an application to the section of the Zoo that takes care of family of cats (Felidae) –(lions , panthers , tigers etc). 
 
Note :  NetBeans IDE 8.2 or higher version can be used to implement lab tasks 
 
1. Create a new general Java application project. Name the project as “CatFamilyApp”. 2. Create two packages to hold class files and GUIs. 3. Create the Cat class (inside Code package) including the following details. 
                      
4. Create a JFrame class called AnimalUI (inside GUI package) including the following details. 
 
        
 
 
 
5. Write a Constructor for the class AnimalUI (The Constructor should initialize the data structure to store a given number of cages) 
 
6. Write a method to add a Cat detail to the details data structure. 
 
public void addCat(String name, String animal, int age) 
 
Properties   private String name;  private String Animal; // Whether it’s a Lion , Panther   public int age; Methods  Constructure   Get methods    
 
 
  
 
                            Properties  private Cat details[];  private int numberOfCages;  private int count; 
   
                             
   
7. Write a method to delete a Cat detail in the array when puppy name is passed, we need to move all the other puppy details with higher index values down one element to fill in the ‘hole’ left by the deleted element. 
 
public boolean deleteCat(String name) 
 
8. Write a method to return the list of the cat names when the animal type is given (Lions / Tigers) 
 
public String getCatList(String animal) 
 
9. Write a method to return the details of the cat when the name is given. 
 
public Cat getCat(String name) // return the object if you can find the puppy , if not return null 
 
 
10. Write a method to update “age” property to update the animals’ age (every year) when name of the animal is passed.  
 
public boolean updateAge(String name,int age) 
 
11. Design a suitable interface, so that Zoo keepers can insert animal details, get the name list , and delete a animal detail when it’s passed away or moved to a different Zoo.

It looks like you're working on a Java project to create an application for managing a family of cats in a zoo. Here's a step-by-step guide on how to implement the requirements you've mentioned:

Step 1: Create a new Java application project in NetBeans IDE and name it "CatFamilyApp."

Step 2: Create two packages to hold class files and GUIs. Name one package "Code" for class files and another package "GUI" for GUI-related classes.

Step 3: Create the Cat class inside the "Code" package. Here's an example of what this class might look like:

java
Copy code
package Code;

public class Cat {
    private String name;
    private String animal; // Lion, Panther, Tiger, etc.
    private int age;

    public Cat(String name, String animal, int age) {
        this.name = name;
        this.animal = animal;
        this.age = age;
    }

    // Getters and setters for name, animal, and age properties
    // ...

    @Override
    public String toString() {
        return "Name: " + name + ", Animal: " + animal + ", Age: " + age;
    }
}
Step 4: Create a JFrame class called AnimalUI inside the "GUI" package for your user interface. Implement the GUI as per your requirements.

Step 5: Write a constructor for the AnimalUI class to initialize the data structure to store a given number of cages. You can use an array or other suitable data structure for this.

Step 6: Write a method to add a cat detail to the details data structure. Here's an example:

java
Copy code
public void addCat(String name, String animal, int age) {
    // Create a new Cat object and add it to your data structure
    Cat cat = new Cat(name, animal, age);
    // Add the cat to the data structure (e.g., an array)
    // ...
}
Step 7: Write a method to delete a cat detail in the array when a cat's name is passed.

java
Copy code
public boolean deleteCat(String name) {
    // Find the cat in your data structure and remove it
    // ...
    // Return true if the cat was deleted, false otherwise
    // ...
}
Step 8: Write a method to return the list of cat names when the animal type is given (e.g., Lions, Tigers).

java
Copy code
public String getCatList(String animal) {
    // Search for cats of the specified animal type and return their names
    // ...
}
Step 9: Write a method to return the details of a cat when the name is given.

java
Copy code
public Cat getCat(String name) {
    // Search for a cat with the given name and return the Cat object
    // ...
    // Return null if the cat is not found
    // ...
}
Step 10: Write a method to update the "age" property to update the animals' age (every year) when the name of the animal is passed.

java
Copy code
public boolean updateAge(String name, int age) {
    // Find the cat with the given name and update its age
    // ...
    // Return true if the age was updated, false otherwise
    // ...
}
Step 11: Design a suitable interface in the AnimalUI class, allowing zookeepers to insert animal details, get the name list, and delete animal details when needed.

These steps outline the basic structure of your Java application. You can further develop and expand on this foundation to create a more robust and user-friendly cat family management system for the zoo.

Write a method to return the list of cat names when the animal type is given (e.g., Lions, Tigers).
ChatGPT
To return a list of cat names when the animal type is given, you can iterate through your data structure (e.g., an array or a list) and filter out the cat names that match the specified animal type. Here's a method to do that:

java
Copy code
public List<String> getCatNamesByAnimalType(String animalType) {
    List<String> catNames = new ArrayList<>();

    // Iterate through the cat objects in your data structure
    for (Cat cat : details) { // Assuming 'details' is an array of Cat objects
        // Check if the current cat's animal type matches the specified animalType
        if (cat.getAnimal().equalsIgnoreCase(animalType)) {
            // Add the cat's name to the list
            catNames.add(cat.getName());
        }
    }

    return catNames;
}
In this method:

animalType is the parameter that specifies the type of animal (e.g., "Lions," "Tigers").
We create an empty ArrayList called catNames to store the names of cats that match the specified animal type.
We iterate through the details array (assuming it holds Cat objects).
For each Cat object, we check if its animal type (retrieved using cat.getAnimal()) matches the animalType parameter, ignoring case.
If there's a match, we add the cat's name (retrieved using cat.getName()) to the catNames list.
Finally, we return the list of cat names that belong to the specified animal type.
You can call this method with the desired animal type (e.g., "Lions" or "Tigers") to retrieve a list of cat names for that specific animal type.

Write a method to return the details of a cat when the name is given.
ChatGPT
To return the details of a cat when the name is given, you can iterate through your data structure (e.g., an array or a list) and find the cat with the matching name. Here's a method to do that:

java
Copy code
public Cat getCatByName(String name) {
    // Iterate through the cat objects in your data structure
    for (Cat cat : details) { // Assuming 'details' is an array of Cat objects
        // Check if the current cat's name matches the given name
        if (cat.getName().equalsIgnoreCase(name)) {
            // Return the Cat object if the name matches
            return cat;
        }
    }

    // If no matching cat is found, return null
    return null;
}
In this method:

name is the parameter that specifies the name of the cat you want to retrieve.
We iterate through the details array (assuming it holds Cat objects).
For each Cat object, we check if its name (retrieved using cat.getName()) matches the name parameter, ignoring case.
If there's a match, we return the Cat object.
If no matching cat is found after iterating through the entire array, we return null to indicate that no cat with that name was found.
You can call this method with the name of the cat you want to retrieve, and it will return the Cat object containing the details of that specific cat.

Certainly! Here's a Java method that returns the details of a cat when the name is given:

java
Copy code
public Cat getCatByName(String name) {
    for (Cat cat : details) { // Assuming 'details' is an array or a collection of Cat objects
        if (cat.getName().equalsIgnoreCase(name)) {
            return cat;
        }
    }
    return null; // Return null if no matching cat is found
}
In this method:

name is the parameter that specifies the name of the cat you want to retrieve.
We iterate through the details array or collection (assuming it holds Cat objects).
For each Cat object, we check if its name (retrieved using cat.getName()) matches the name parameter, ignoring case.
If there's a match, we return the Cat object.
If no matching cat is found after iterating through the entire array or collection, we return null to indicate that no cat with that name was found.
You can call this method with the name of the cat you want to retrieve, and it will return the Cat object containing the details of that specific cat.
