package com.codegym.task.task06.task0619;

public class Solution {

    public static String solution;

    public static class Cat {
        public static String cat;
    }

    public static class Dog {
        public static String dog;
    }

    public static void main(String[] args) {

    }
}
If i do 
String Solution.name, String Cat.name, String Dog.name
also a mistake
