7 Multiple inheritance using Interface

// inheritance using interface
interface base{
    int x = 22;
}
class Main implements base{
    public static void main(String args[]){
        Main obj = new Main();
        System.out.println(obj.x);
    }
}
// output 22

// multiple inheritance using interface
interface AnimalEat {
   void eat();
}
interface AnimalTravel {
   void travel();
}
class Animal implements AnimalEat, AnimalTravel {
   public void eat() {
      System.out.println("Animal is eating");
   }
   public void travel() {
      System.out.println("Animal is travelling");
   }
}
public class Demo {
   public static void main(String args[]) {
      Animal a = new Animal();
      a.eat();
      a.travel();
   }
}
/*
Output
Animal is eating
