Scanner IN = new Scanner(System.in); String grandFatherName = IN.nextLine(); String grandMotherName = IN.nextLine(); String fatherName = IN.nextLine(); String motherName = IN.nextLine(); String sonName = IN.nextLine(); String daughterName = IN.nextLine(); Cat grandfather = new Cat(grandFatherName,null,null); Cat Grandmother = new Cat(grandMotherName, null, null); Cat Father = new Cat(fatherName,grandfather,null); Cat Mother = new Cat(motherName,null,Grandmother); Cat Son = new Cat(sonName,Father,Mother); Cat Daughter = new Cat(daughterName,Father,Mother); this is the solution...
