Is this right?

Actually just catCount++; will be enough: public static void addNewCat(){ catCount++; } Main: public static void main(String[] args){ addNewCat(); addNewCat(); addNewCat(); System.out.println(Cat.catCount); }

It is easier if you just add this: public static void addNewCat() { int addNewCat = catCount ++; }

package com.codegym.task.task04.task0404; /* Cat register */ public class Cat { private static int catCount = 0; public static void addNewCat() { int h=1; catCount+=h; System.out.println(catCount); h++; //write your code here } public static void main(String[] args) { addNewCat(); addNewCat(); addNewCat(); } } here i called 3 times and i got incremented 3 times .....i.e.. i printed the number and then i incremented :) i hope it will helpfull

public static void addNewCat() { //write your code here Cat cat = new Cat(); //remove this line, everytime you call Cat.addNewCat(); you are creating a object called cat, calling this method again is creating the same object called cat, catCount++; } instead create your objects in the main class public static void main(String[] args) { Cat cat = new Cat() Cat.addNewCat(); Cat cat2 = new Cat() System.out.println(catCount); }

I don't know what your goal is but this is alright. Everytime you call the addNewCat() method you will create a new Cat object and increment the static catCount variable by one.
