What is the result of compiling and running this program?

class Mammal{
      void eat(Mammal m){
            System.out.println("Mammal eats food");
      }
}
class Cattle extends Mammal{
      void eat(Cattle c){
            System.out.println("Cattle eats hay");
      }
}
class Horse extends Cattle{
      void eat(Horse h){
            System.out.println("Horse eats hay");
      }
}
public class Test{
      public static void main(String[] args){
            Mammal h = new Horse();
            Cattle c = new Horse();
            c.eat(h);
      }
}

When class Cattle extends class Mammal, then the method eat() is not overrided but overloaded. That means the class Cattle now has two method :
1-> eat(Mammal m)
2-> eat(Cattle c)

Similarly when Horse extends Cattle, then the method are not over ridden because of the different signature i.e. different parameters.

So when c.eat(h) is called then c is referencing to Horse object so we look in Horse class.. where we find three method..
1-> eat(Mammal )
2-> eat(Cattle )
3-> eat(Horse )

Now h is refererring to mammal, so eat(mammal) will be executed

here simply eat method called by passing h type parameter that is Horse so it will be bind with Horse class eat method beacuse method parameter is Horse type

Hello everyone. ..I m new in java..I want to ask that how to create object from 2 different class or can any one dicuss the above program specially " cattle c=new horse(); " they have usef cattle and horse both how can be..
