Utilize var syntax for some local variables in some java files

[ghost]

What is it?

• Codebase improvement (dev facing)

Description of the changes in your PR

• Utilize var syntax for some local variables in some java files
• In most places it is conservative

Kotlin isn't going to come for most of files (especially big) in near time but java also has var so it is a small step toward clarity of kotlin.

I expect you will say it is too stupid and I will even agree so just close this PR right away if you feel so. I won't be pouting :3

Hi, thanks for the PR but sadly this doesn't seems particularly useful since we will eventually move to Kotlin this year. I will be closing this as won't do.
