You probably know a lot more about the company you work for than other companies you might invest in, so that might be one reason to prefer their stocks

"It is easy to notice that in Java, one might have implemented infinite number of for loops trying to do such lookups using iterators."

??

val list3 = list1 ::: list 2 // returns a new list of 6 elements

final list3 = new ArrayList(list1).addAll(list2);

list3.drop(2) //return a new list without first 2 elements

new ArrayList(list3.subList(2));

list3.filter(s => s > 4) //return a list with elements 5 and 6

new ArrayList(list3.subList(4));

Also the Java versions use standard convenience methods which seems preferable to language features since anyone can re-implement them, or add new ones. Plus the copy-on-mutate behaviour is optional.

Note the dreadful UI on their app implementation! (You type something like '100:5,25,60' and invite someone to guess a number on each round)

Why wouldn't they do something like:

1. Enter the subtotal (becomes permanently printed at the top) 2. Enter successive item amounts, after each entry the app says 'pay' or 'continue'

I had a similar problem - also dismissed Twitter4J etc. as too complicated and wrote a 50 line Java method to send a tweet (signature: tweet(tweet, consumerKey, consumerSecret, accessToken, accessTokenSecret) ).

So presumably it's the culture you don't like, rather than the language.
