Yeah but you can chain it so it makes things a lot more readable:

foo?.bar?.getResult()?.toString()

Nice! That's a cool little operator.

a bit late but yeah.. Valentin answerd already but ?. checks for null and prevents null pointer exception and returns null for value but also ?? is null coalescing operator which in case something returns null takes right side value as in java ternary operator but this one's shorter so nullvaluestring ?? "somedefaultvalue" looks a bit prettier :D
