Is there a graph or visualization for showing the frequency of relations between nodes? e.g. Products commonly bought together

guys, after programming in java for couple of days, how does this even make sense to anybdoy

Had you never done it before @istvan?

well, i just sent patches to fix broken code, or occasionally wrote some code for interviews and web services

after watching a java programmer friend i just realised that i write Clojure in Java 🙂

lol

just start writing some AbstractFactories and StrategyBuilders

😄

AbstractStrategyBuilderFactoryInterface

And AbstractFactoryStrategyBuilderFactory

yes that helps!

but seriously, there are some things that help, like Project Lombok (https://projectlombok.org/), JavaSlang (http://www.javaslang.io/)

you can totally do pretty functional Java these days and use a more declarative style with annotations etc to save on writing code

i was not sure why the average java code is so convoluted and complex and just feels so bad, but i just realized that people spend significant time to make code work for use cases that will never be used

thanks i will check these out

i recently discovered some java 8 niceness:

private static Set<String> validEvents = Stream.of(
            "webpageview",
            "webuiaction",
            "webserveraction",
            "gitclientaction"
    ).collect(Collectors.toCollection(HashSet::new));

seems like a rather convoluted way of creating a Set 🙂

😄

jstaffans how would you do it?

i know only .add() and this one

but if there is something else

I would use ImmutableSet from the Guava library:

Set<String> events = ImmutableSet.of(”a”, “b”, “c”);

alright using Guava makes sense

what is the membership lookup time complexity and do i need to handle an exception when it does not have the item i am looking for?

well i guess if I do 5 items it wont matter that much

I’ll defer you to the Java SE reference docs for that 🙂

😉
