You can call apply
on the input argument directly:
def foo(args: String*) = args(1)
質問
I'm having hard time trying to get nth element from the varargs sequnce in scala. Here's my code
def foo(args: String*) = args.toArray(1)
I receive error like:
error: type mismatch;
found : Int(1)
required: scala.reflect.ClassTag[?]
def foo(args: String*) = args.toArray(1)
What's interesting, code like this works great:
def foo(args: String*) = args.toArray.apply(1)
I'm pretty new to scala but I thought that it should be exactly the same. Is using apply right way to select nth element from vararg seq?
