Setting the number of cats

Be careful what the last condition says. The keyword here is set, NOT increase. The passed integer sets the declared integer up. End. I did not pay attention and I set up the method to throw the number taken inside the variable, which increases the number, it doesn't just set the number up. What I did was "variable is variable + passedInteger "; Pay attention. :)

Here you can find the explanation: https://stackoverflow.com/questions/11664522/why-cant-we-use-this-keyword-in-a-static-method

The Cat class's setCatCount method must set the value of the catCount variable equal to the passed argument. jst read the last requirement you will know what to do. Cat c = new Cat(); c.setCatCount(5); you need to just assign pass value to static var.

I don't see how this is different from the previous problem. If I send a value to setCatCount from 'main" like: public static void main(String[] args) { Cat cat = new Cat(); cat.setCatCount(4); The value of catCount in the setCatCount method is 4, but the value of catCount in the main method is still 0. I used a similar approach in the previous problem and it worked, but it's not working here. Using 'this." doesn't work.

<aybe this is a silly question, but: When should we know when to use this.blablabla and the overall class.blablabla? ex. this.catCount v.s. Cat.catCount?
