Instantiating interfaces in Java

Question

I have this interface:

public interface Animal {
    public void Eat(String name);
}

And this code here implements the interface:

Answer 1

To have a wider picture :

Animal [] Zoo = new Animal[10] ; // is also correct

but why ?

The whole idea is that in the table above you can put 10 animals of different types. The only conditions for this is that all the animals entering the Zoo must implement the interface Animal .

public interface Animal {
 void Eat();
}
class Wolf implements Animal {  void Eat (){ 
System.out.println("Wolf eats meat ") ;}}

Class Zebra implements Animal{ void Eat (){
System.out.println("Zebra eats the grass ") ;}}

class test {
public static void main (String args []) {

Animal [] Zoo = new Animal[2] ;

Zoo[0] =  new Wolf() ;
Zoo[1] = new Zebra() ;

 //so you can feed your animals in Zoo like this

 for (int i=0 ; i
