Requirements:

The program should read in the names of 6 cats in the specified order.
The main method should create 6 Cat objects.
The program should display 6 lines with information about the cats.
The line about the grandfather (first line) must match the conditions.
The line about the grandmother (second line) must match the conditions.
The line about the father (third line) must match the conditions.
The line about the mother (fourth line) must match the conditions.
The line about the son (fifth line) must match the conditions.
The line about the daughter (sixth line) must match the conditions.

useful

1) You just need 3 Cat class variables for name and parentMother + parentFather. 2) You just need two constructors in the Cat class, with one passed argument and three. 3) Your if in the toString() method needs to check for null in both parentMother and parentFather. 4) When creating the catGrandma and catGrandpa objects in the main() method, try to use the three variable constructor and pass null to parentFather and parentMother parts.

useful

You are overcomplicating things here. All you need is 3 instance variables: name, mother and father. Also, you don't even need the second constructor. For fatherCat and motherCat you can use the one with one argument and then just set their father/mother variable accordingly. You can make a setter method if you want a more "clean" solution (setMother(), setFather()), but it is not necessary to pass the test. I hope this helps! EDIT: Or you can pass null to the constructor as another way of doing it.
