Why does this code work?

Question about the task

Implement the fight method

Java Syntax, Level 5, Lesson 5

Under discussion

if (this.age > anotherCat.age || this.weight > anotherCat.weight || this.strength > anotherCat.strength){
    return true;}
else return false;
}

After all, objects were not created. And how will

anotherCat.age

work if we do not even have this class ???

You should use && instead ||. Try:

public boolean fight(Cat anotherCat) {
       //write your code here
       if (this.strength >= anotherCat.strength && this.age >= anotherCat.age && this.weight >= anotherCat.weight ){
           return true;
       }
       else
       {
           return false;
       }
   }

The code above says that if any one stat is greater than the other cat's then that cat wins (return true), so if the two cats fighting had stats like this: cat1: age = 1 weight = 5 str = 12 cat2: age = 3 weight = 7 str = 10 then cat1.fight(cat2) would equal true because str 12 is greater than str of 10 and cat2.fight(cat2) would equal true because both age and weight are greater than cat1's age/weight This task specifically says that if you have two cats and fight them, then only one can win no matter which way that the code is called: if cat1.fight(cat2) is true, then cat2.fight(cat1) MUST BE false. As to anotherCat.age/weight/str... the object is passed into the method as an argument. When the method is called in the code you would pass a second cat object into the method and that would be "anotherCat" inside the method. You should read up a little on methods, here is a good webpage: https://www.geeksforgeeks.org/methods-in-java/
