we also did Linked Lists I think

put that inside the method?

the entire method? @ThisIsChris

I'd put the `try` at line 148, just before the while loop, don't want that thing to go on catching exceptions forever waiting for the loop to break

so put the entire loop inside it?

so
```java
try {
//lines 149-163, the whole outer while loop, until just before the function ends
}
catch Exception {
//leave blank because we're supposed to assume nothing will happen
}
//then exit the function
}
``` @Jacob

thanks

okay now I have a new exception

here is my new code

```java
------------------testAddLast()----
Exception in thread "main" java.lang.NullPointerException
at MyLinkedList$ListNode.access$2(MyLinkedList.java:11)
at MyLinkedList.add(MyLinkedList.java:205)
at MyLinkedListTester.testAddLast(MyLinkedListTester.java:42)
at MyLinkedListTester.main(MyLinkedListTester.java:214)
```

@ThisIsChris

That's good, different errors now

Unfortunately it's 2am here so I have to get to bed

okay thanks for your help

good night

good night

by the way

for googling purposes

what I suggested with "try to see if it works, catch an exception if it doesn't" is called "duck typing" so for more info you can google "duck typing in java"

The idea of a function that can take in anything that implements a function (like the sort function that works on any node data that implements a `compareTo` function) is called "polymorphism"

though googling "polymorphism in Java didn't present any helpful examples to your problem, maybe you'll have better luck

ok good night

thanks a lot

good night

@ThisIsChris When you run the Reddit script, do you also get a bunch of duplicate comments?

I'm trying to figure out how to fix it right now

you can keep a (global) list or set with the text of every comment you've printed before, so that if the text is already found in your list of already printed comments, then you don't print it.

There's a few slightly more optimized ways to do it, but that would be the laziest fastest to implement

hmm ya that's what I'm trying to do

@Jacob what difficulty are you running into?

I added this in interested_comments():

interesting_list = []

and then I modified the if statements to be like this

if "white" in comment_set and {"priviledge", "privilege", "privledge"}.intersection(comment_set) and comment not in interesting_list:

I think I can figure this out, though

@ThisIsChris I'm testing out my solution right now

In the meantime, I have some new ideas

How difficult do you think it would be to add this functionality? Detect what specific immigration topic is about, and automatically suggest counterarguments from a database.

Maybe I could put the arguments in a list, and look for phrases like "jobs Americans won't do" and the script would immediately pop out a refutation

I think it would be pretty straightforward. You need a list keywords/key phrases that indicate the topic of conversation, then you just need a pre-written counter argument for each topic
