Array in Java

Question

I have to make a Dog list class that is in an array form,
I need to have an adding method that adds a dog to my list (array)
I need to have a removing method that removes a dog from my list(array)
I also need to check if a dog exists in my list (array)
Please help me out with the methods
I have a hard time knowing How to make them work

Answer 1

You would have a field in your DogList class to store all the dogs:

private List<Dog> dogList = new ArrayList<>();

Your method signatures might look like this:

void addDog(Dog dog) { }

void removeDog(Dog dog) { }

boolean dogExists(Dog dog) { }

Answer 2

If you have an array of dogs, then you can loop through the array and check each element if it equals to the dog that you are looking for.

Answer 3

we are allowed only to use Array .
Yes I did those basics but I don’t know whst to put in the methods you know how can I check if a dog exisys for example.
