This is a program im writing for class. Here is the exception im getting: Exception in thread "main" java.lang.NullPointerException at LinkedList_final.insert(LinkedList_final.java:72) at LinkedList_final.main(LinkedList_final.java:247) Basically, my program reads a text file and parse a string. And then, add the string to Linked list. Thank you for your time and any help …
