Unsure of how to solve the last step.

Question about the task

Static cats

Java Syntax, Level 6, Lesson 11

Under discussion

If someone can walk me through the last step it would be greatly appreciated.

1. In the Cat class, add the public static ArrayList<Cat> variable cats.
2. Each time a new cat (new Cat object) is created, add it to the variable cats. Create 10 Cat objects.
3. The printCats method should display all cats on the screen. You need to use the variable cats.

Requirements:

Add the public static ArrayList<Cat> variable cats to the Cat class.
The variable cats must be initialized.
The main method should create 10 Cat objects (use the Cat() constructor).
The main method must add all the created cats to the variable cats.
The printCats method should display all the cat objects in the variable cats. Each on a new line.

There´s no need to create a unique name, if you wish so:

for (int i=1; i<=10;i++){
            Cat catMember = new Cat();
            cats.add(catMember);
        }

The constructor for Cat should be:

public Cat() {
}

but the constructor in the code above is:

public Cat(ArrayList<Cat> cats) {
   Cat.cats = cats;
}

This is what is failing

You just need to create 10 Cat objects with unique names and add those objects to the ArrayList. For example:

Cat fluffy = new Cat();
        cats.add(fluffy);
