Hi vishnu, I see a couple of minor errors

  1. you have a small syntax error inside your getInfo() method, you have misspelled $this->flavor as $hits->flavor
  2. your getInfo() method is placed outside of your Trout class, you need to put it before the closing curly bracket of the Trout class

By rectifying these small errors your code should work fine :)

Hope that helps!!
