This goes way over my head.

lines 23 and lines 26, which constructor would those lines be calling? What does that constructor do? Answer these two questions and you should be able to figure out the bug.

They are calling the same constructor. I don't know how to make them call different constructors. Please help

Both of them are calling the constructor that accepts a name and a father. Line 23 is sends a name and a father, line 26 sends a name and a mother. If that constructor only sets a father, then it can't be used for both lines 23 and 26. You need to fix this.

solution

I would get rid of it completely and use only the constructor at line 60: line 60 constructor takes in (Name, mother, father) in that exact order. You can pass in the value 'null' for either mother or father if need be. For example, line 23 would be:

Cat catFather = new Cat(father, null, grandFather);
