It sounds like you have a Java formatter configured (by default?) and VSC is applying it to your code automatically (on save?).

# How code is formatted
If your only gripe is these specific stylistic choices, but you do want auto-formatting for other things, you must figure out what formatter is being used, how it's configured, and what features it supports for customizing the style.

The example you give for `if` is very common across languages. I agree with you that it's silly, but most authors of code formatters are very opinionated on this and refuse to allow single-line `if` conditionals because supposedly they reduce readability. As you aptly show, the opposite is often the case. Hopefully your formatter supports disabling it.

The second example probably has to do with the formatters "max line length" setting. This is generally a good idea, but you can usually disable it or set to a higher limit.

To find the settings, open the settings UI (you can find it in the command palette) and search for "java" in the top bar. You should see some formatting related hits, probably in a section called `Extensions -> Java` (each language gets its own extension in VSC).

You can also try to use a different Java formatter, I'm sure there's several (VSC should have a "formatter path" config key).

# When formatting is applied
VSC can apply formatting on demand (see command palette) or automatically on save. For the latter, look in preferences for `Format On Save`.

Keep in mind that VSC auto-saves as you type by default, so if you're surprised why it keeps reformatting without you pressing `Ctrl+s`, this is why.
