Question about the task

Cat relations

Java Syntax, Level 6, Lesson 11

Resolved

The line about the father (third line) must match the conditions. although output looks correct to me.

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:
The cat's name is Grandfather Tiger, no mother, no father The cat's name is Grandmother Puss, no mother, no father The cat's name is Father Oscar, no mother, Grandfather Tiger is the father The cat's name is Mother Missy, Grandmother Puss is the mother, no father The cat's name is Son Simba, Mother Missy is the mother, Father Oscar is the father The cat's name is Daughter Coco, Mother Missy is the mother, Father Oscar is the father

solution

Hi Nikhil, welcome to CodeGym. It is very important that you solve the problem AND meet all the requirements if you want to get past the validation/verification. As part of the new task... each Cat has a Mother AND a Father. That suggests you can no longer use the Constructor for a Cat who has a Mother only like you do in both catFather and catMother. Try instead using the new one you created (String, Cat, Cat) setting to null the missing parent. You probably should also revert the (name, Cat) constructor to its original form (not sure, if you can remove it entirely.. just don't use it). Keep the solution simple and let me know if you have further trouble.
