How to get nth element from varagrs sequence

Question

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?

Answer 1

You can call apply on the input argument directly:

def foo(args: String*) = args(1)
