solution

#1 The toString() is incorrect. When I ran this code I entered names of my family members for the user input and all the outputs used the same tempate: "The cat's name is {UserInput}, no mother, no father" It should have printed exactly like the example excepting the names that I used instead. You will need to revisit this method so that it can output the correct information for: Grandfather Grandmother Father Mother Son Daughter #2 The task says that the Cat class should have a name, a mother, and a father. The Cat class from this code has name, parent, mother, father. This will need to be corrected because when you pass GrandMother and Grandfather to the constructor with "parent", how do you know what parent it is?? Unless you name it "Grandmother ...." or "Grandfather ...." (and the user won't do this), there is no way to tell. I would suggest saving this code then resetting the task. You can paste the code from the main method of this code back into the reset task. You would then just need to fix the cat class to address the above issues. Resetting the task allows you to see the previous toString() method that was there. Look at how they handled the output when there was either a parent or not a parent. It shouldn't be hard to add one more condition to that to get the proper output to pass this task.

Glad I was able to help. These tasks are not difficult when you have solved them 5 different ways, however, to reassure you, I personally failed many of these tasks multiple times the first time I attempted them too. Some more than 20 times.
