Can someone tell me why sometimes people are including class C{public static void main(String[]a){...}}
and sometimes that seems to be not necessary?(https://codegolf.stackexchange.com/a/62373/46569)

Whenever submissions are required to be full programs, Java's standard boilerplate code (i.e. class
and main
, etc.) is required. When submissions are allowed to be functions, this boilerplate is not required.

2\$\begingroup\$ @VoteToClose I can't imagine a situation where the OP would require boilerplate for a function (thereby making it a full program) or not require boilerplate for a full program (thereby making it a snippet, which aren't allowed by default). \$\endgroup\$ – Alex A.

\$\begingroup\$ When it's a function, that doesn't mean just a function body though. So you still need the function header and whatnot, even though you don't need the rest of the boilerplate. \$\endgroup\$ – SuperJedi224 Nov 18 '15 at 20:16

\$\begingroup\$ Thanks for your answers, I actually completely missed the "write a program or function" \$\endgroup\$ – Joba Nov 18 '15 at 21:02

\$\begingroup\$ @VoteToClose Except that the default is the other way around. If not specified, functions are fine: meta.codegolf.stackexchange.com/q/2419/14215 \$\endgroup\$ – Geobits Nov 19 '15 at 14:08
