how to concatenate option in scala -

-

what's elegant/right way in scala string concatenate option none renders empty string , variables have value don't wrapped in some("xyz")

case class foo(bar: option[string], bun: option[string]) println(myfoo.bar+ "," + myfoo.bun)

the output want example

hello,

instead of

some(hello),none

to value option in safe way use getorelse , provide default argument, used in case option none. in example this:

case class foo(bar: option[string], bun: option[string]) println(myfoo.bar.getorelse("") + "," + myfoo.bun.getorelse(""))

then you'll required result
