     Same problem as your other post about hexadecimal and

Please read the Oracle article
"Code Conventions for the Java Programming Language"
on the web.

Proper formatting and commenting will make learning
and debugging much easier.

Oops. Looks like that has been deprecated.
You might start with "Google Java Style".

Not deprecated.

Oracle just made a note about it not having been updated and
that the content *may* not be valid.

But people are still using it.

With some extrapolation for the language elements added
in later Java versions.

Deprecated or not, it's still a great starting point.
