Is there a way to...

Is it possible to check whats in an array and compare everything to one string?

 

Loops.

 

I was using one but i kept getting a NullPointerException on a line a used an if statement with it.

 

Probably because the current element you're comparing is set to null and you can't call methods on null pointers just add a var != null check before using methods.

 

Thanks for the help. Also, for some reason if i add multiple quizzes for some reason it executes the first if statement instead of the second(I left a note at the place where they are). Do you know what might be causing this?
