What should I change in my code? pls, help!

Question about the task

Cats in the Universe

Java Syntax, Level 4, Lesson 2

Resolved

Hi people, Can anyone give me some tips about my code? Thank you in advance!

Write code to correctly count the number of cats created (count) and display the correct number of cats 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 be a static int, have a public access modifier, 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 com.codegym.task.task04.task0407; /* Cats in the Universe */ public class Solution { public static void main(String[] args) { Cat cat1 = new Cat(); cat1.count = 1; Cat cat2 = new Cat(); cat2.count=2; Cat.count++; System.out.println("The cat count is " + Cat.count); } public static class Cat { public static int count = 0; } }

Another wrong solution was looked like: public static void main(String[] args) { Cat cat1 = new Cat(); cat1.count = 1; Cat cat2 = new Cat(); cat2.count=2; Cat.count = cat1.count+cat2.count; System.out.println("The cat count is " + Cat.count);

Actual cat count should be 2 because there is only two cat in the main method but your program counts the cat as 3.

No, it's not a solution in there. I changed the value by adding 1 to each object and the result was 2 cats, although the task has not been considered as completed. There must be another way to resolve it. Anyway, TY for response.

solution

No not like that, read the requirement carefully they ask to count the number of cats created (count). May be increment the cat after you initialize with the created cat object,try like this

Cat cat1 = new Cat();
       cat1.count ++;

       Cat cat2 = new Cat();
       cat2.count++;

      // Cat.count = cat1.count+cat2.count;

       System.out.println("The cat count is " + Cat.count);

Thank you, dhanush! Indeed, I didn't get the requirements right and as a result, I wasn't able to find out the solution. Case closed :)
