[HW#2] NullPointer Exception #157

Closed TFloyd1989 closed 4 years ago

TFloyd1989 commented 4 years ago

I keep getting a null pointer exception whenever I try to add to the string list of any given node. How do I add to it so that it stops giving a null pointer exception?

marvinquiet commented 4 years ago

Did you find out what caused this exception? I assume you visited some null character nodes.

TFloyd1989 commented 4 years ago

Yes, I was able to figure it out

marvinquiet commented 4 years ago

Then, just avoid accessing the null node would help
