Study Java and learn how to check the results of method calls, and not to assume that they will always succeed. Which line of the above code snippet is line 36?

That is a standard error in all languages. You have a reference object that does not point to anything: a NULL pointer. Look at the line where it occurred and that should identify the bad reference item.
