[BUILD][MINOR] Fix java style check issues

## What changes were proposed in this pull request? This patch fixes a few recently introduced java style check errors in master and release branch. As an aside, given that [java linting currently fails](#10763 ) on machines with a clean maven cache, it'd be great to find another workaround to [re-enable the java style checks](https://github.com/apache/spark/blob/3a07eff5af601511e97a05e6fea0e3d48f74c4f0/dev/run-tests.py#L577) as part of Spark PRB. /cc zsxwing JoshRosen srowen for any suggestions ## How was this patch tested? Manual Check Author: Sameer Agarwal <[email protected]> Closes #20323 from sameeragarwal/java.
