At the end of Fairy Tail it is confirmed that Levy is pregnant with a child. In the 100 Years Quest continuation of the story Levy is still pregnant.
Fairy Tail's animation ends with a happily ever after for Gajeel and Lucy. These two finally reunite after being torn apart and Levy cannot help but break down in another show of emotions. Understandably, considering she believed her loved one had died.
2 Answers. The add() method on HashSet will return false if a value has already been added to the set. The method above uses this to detect that a duplicate has been found and then removes the duplicate from the HashMap by using the remove() method on the iterator.
Set is not allowed to store duplicated values by definition. If you need duplicated values, use a List. As specified on the documentation of the interface, when you try to add a duplicated value, the method add returns false, not an Exception.
