The Cat class must have only one count variable.

Question about the task

Under discussion

for me it seems like the code looks pretty good and i literally have only one count variable... so what am I missing here?

Write a code that correctly counts the number of created cats (count) and correctly displays the count on the screen.

Requirements:

The program should display text on the screen.
Don't change the line responsible for screen output.
The Cat class must have only one count variable.
The Cat class's variable count must have the public modifier, be an int, be static, and be initialized to zero.
The main method should have only two initialized Cat variables.
The variable count must store the actual number of cat objects created.

package en.codegym.task.jdk13.task04.task0407; /* Count the number of cats */ public class Solution { public static void main(String[] args) { Cat cat1 = new Cat(); //write your code here Cat cat2 = new Cat(); //write your code here System.out.println("The cat count is " + Cat.count); } public static class Cat { public static int count = 0; public Cat() { Cat.count+=1; } } }

What you did works but unfortunately was not what CodeGym asked. They didn't want you to modify the Cat class at all. Imho it should just contain

public static class Cat {
    public static int count = 0;
}

With the constructor and writing count a second time you probably triggered that mistake. Spoiler: they want you to increment the count variable from within the main method each time you create a Cat object, right after:
