Hi Ahmet, Your code is throwing a NullPointerException because you are attempting to use a reference that has not been initialized (other than to null). In your generateNewName method, newName is declared and initialized to null. In the for loop that follows you attempt to assign a value to the first element of the newName char array, but it is not an array at this point, it is null. You need to find some way to initialize your char array before entering the for loop. Once you do the NullPointerException will clear up.
Hope this helped. Happy coding!
