I don't get it

Question about the task

Resolved

I wrote down the code for the task on Eclipse and it runs as it is just fine. It doesn't even needs the "@override" bit. However when I bring the code here it gives me a different result that does not work. Can ayone help me understand why?? thanks in advance yall are great!

Task: Each cat has a name and a mother.
Create a class that describes this situation.
Create two objects: a daughter cat and a mother.
Display them on the screen.

New task: Each cat has a name, a father, and a mother.
Edit Cat so that it reflects these relationships.
Create 6 objects: grandfather (the father's father), grandmother (the mother's mother), father, mother, son, daughter.
Display them all in the following order: grandfather, grandmother, father, mother, son, daughter.

Example input:
Grandfather Tiger Grandmother Puss Father Oscar Mother Missy Son Simba Daughter Coco

Example output:

useful

line 17 passes in granPa. The constructor on line 35, that uses the arguments (String, Cat) sets the cat to mother. Using the example inputs this would means daddyCat has a mother named "Grandfather Tiger" and father would be null. You need to fix this. Also there is an error in the toString method on line 47 where it is outputting the full mother information when there is a mother.
