Still do not get it..

Question about the task

Resolved

What I also do not understand is that you make a cat1 and a cat2 object. you fill the object with data: strength, age, weight. and then a complete another object (anotherCat) can use the data of cat2. I hope you can help me..

Ok Sabine, though you understood but in simple words here again. In anotherCat variable, reference of cat2 is being passed i.e. it's attributes, so that they can be compared with the current cat object i.e. cat1 Also, why cant you do this and compare i and j based on the values added . i and j are local variables in the method fight int i=this.weight+this.strength+this.age; int j=anotherCat.age+anotherCat.weight+anotherCat.strength; Additionally I'd like to understand the significance of this code please public Cat() { this.age = age; this.weight = weight; this.strength = strength; }

useful

This Cat anotherCat doesn't create an object. anotherCat is just a variable of type Cat, and it can hold the reference of any object of Cat class.

Cat someCat; // create a variable of type cat
someCat = new Cat("apple"); // create a cat object, give that cat a name(apple), assign the reference of
                                               //that cat object to "someCat" variable.
someCat = new Cat("mango"); // create cat object give that cat a name ( mango), assign the reference of
                                               //that cat object to "someCat" variable.

Cat otherCat = someCat; // now otherCat variable also has the reference of the same object that someCat //has

similary when we do cat1.fight(cat2), this is what happens :

Cat anotherCat = cat2;

If you understand now, then please give a response.
