what is the problem here?

public class Solution { public static void main(String[] args) { Animal e= new Cow(); System.out.println( e.getName() ); } abstract static class Animal { public abstract String getName(); } static class Cow extends Animal{ private String name; public Cow() { this.name = "first cow"; } @Override public String getName(){ return name; } } }

can someone explain me what im doing wrong I dont understand this task is so frustrating

public class Solution {
    public static void main(String[] args) {
   Animal e= new Cow();
   e.getName();
   }

    abstract class Animal {
        public abstract String getName();


    }

    public static class Cow extends Animal{
     public static String getName(){ String s="Cow"; return s;}


    }

}

move the classes to solution class make them public static

move both those classes to the Solution class and make them static
