How to convert String to Long in Kotlin?

Answer 1

It's interesting. Code like this:

val num = java.lang.Long.valueOf("2");
println(num);
println(num is kotlin.Long);

makes this output:

2
true

I guess, Kotlin makes conversion from java.lang.Long and long primitive to kotlin.Long automatically in this case. So, it's solution, but I would be happy to see tool without java.lang package usage.
