is there something I’m completely missing about using a while loop within a for loop? The while loop is looping over a list of JSwing nodes, the for loop is iterating over a list of items but the for loops only runs a single time then just does not loop, I don’t get it. I originally tried a foreach, and now I’m just adding print statements to try to understand what I’m doing wrong. I know this code is not the cleanest/most correct lol. Learning Kotlin as I go

hard to debug someone else's code, but idx should increment. So what happens? You just go past the try? Do you catch an error?

thanks @Michael de Kaste! I ended up running it through the debugger and still not sure of what was causing issue in first place but reworked some code and it loops as expected 🤷‍♂️

aside: I'd convert that Enumeration into anything else first...using

Collections.list()

maybe. or maybe there's a asSequence adapter you can use/write

appreciate it, I’ll look to do that. Is there specific performance or readability reasons for the change?

Enumerations are just very...Java 1.0. doesn't look like you can even use them directly in for-each, right? manually iterating things can be a source of errors

lol I’m not entirely sure myself, I found a project to use Kotlin on to also learn some about the JVM. Loving Kotlin so far, but I’m very much in the early stages of my understanding

if you pasted another version with all the debug statements and commenting code removed, and enabled Kotlin syntax highlighting...that would make it easier for others to read.

for this problem 😄 onto other ones of my own making with lack of understanding. Thanks again for the help and pointers!
