Hint for class 7 execise 4

Sorry, but changing the test condition isn't a valid solution. :smile: 

To correctly solve the exercise, the OrangeTree class needs a `==` method. See the provided method stub above.

Think about the work that should live inside the `==` method. To correctly solve the problem, it will look very similar to the code below.

```ruby
OrangeTree.new(20).fruit == OrangeTree.new(20).fruit
```
