Не могу найти описание переменной "motherName" в классе "com.javarush.task.task06.task0621.Solution.Cat". Возможно вы забыли ее импортировать (указать в import).
package com.javarush.task.task06.task0621;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
/*

*/
public class Solution {
public static void main(String[] args) throws IOException {
BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
String motherName = reader.readLine();
Cat catMother = new Cat(motherName, catMother, null);
String fatherName = reader.readLine();
Cat catFather = new Cat(fatherName, null, catFather);
String daughterName = reader.readLine();
Cat catDaughter = new Cat(daughterName, catMother, catFather);
String GrandFatherName = reader.readLine();
Cat catGrandFather = new Cat(GrandFatherName, null, null);
String GrandMotherName = reader.readLine();
Cat catGrandMother = new Cat(GrandMotherName, null, null);
String sonName = reader.readLine();
Cat catSon = new Cat(sonName, catMother, catFather );
System.out.println(catGrandFather);
System.out.println(catGrandMother);
System.out.println(catFather);
System.out.println(catMother);
System.out.println(catSon);
System.out.println(catDaughter);
}
public static class Cat {
private String name;
private Cat catMother;
private Cat catFather;
Cat(String name) {
this.name = name;
}
Cat(String name, Cat catMother, Cat catFather) {
this.name = name;
this.catMother = catMother;
this.catFather = catFather;
}
@Override
public String toString() {
if (catMother == null || catFather == null)
return "The cat's name is " + name + ", no mother ";
else
return "The cat's name is " + name + ", mother is " + motherName;
}
}
}
