interface B 
{
   public void print();
}
interface C
{
   public void print();
}
public class HybridInheritanceDemo extends A implements B, C
{
   public void print()
   {
      System.out.println("implementing print method");
   }
   public void show()
   {
      System.out.println("show method of class HybridInheritanceDemo");
   }
   public static void main(String[] args) 
   {
      HybridInheritanceDemo obj = new HybridInheritanceDemo();
      obj.show();
      obj.print();
   }
}
