>
> Key: LUCENE-8975
> URL: https://issues.apache.org/jira/browse/LUCENE-8975
> Project: Lucene - Core
> Issue Type: Improvement
> Affects Versions: 8.2
> Reporter: Koen De Groote
> Priority: Trivial
> Fix For: 8.3
>
> Time Spent: 40m
> Remaining Estimate: 0h
>
> Simple, non-important code cleanup.
> Again, to clarify, please don't bother yourself with this ticket on company
> time, on personal time you could be working on something that makes you money
> or improves the product for your feature personally.
>
> This entire ticket is an afterthough. A look back at the code base that most
> people don't have the time for.
>
> ================
>
> While true that using `entrySet()` is really only an improvement for
> traversing a TreeMap(at least that's how it was in JDK8), it's a good
> practice in general to use it over keySet(), if you then use that keyset to
> do an extra lookup to get the value as well as the key.
>
> So that's what this ticket is.
>
> All changes were done automatically via Intellij's built-in code analysis.
>
> Putting this on LUCENE because code both in lucene and solr was changed.
