java vs scala - which is easier to read?

// Compute Fibonacci numbers, ex: 1 1 2 3 5 8 13 21...
// A fib number is the result of adding the previous two,
// such that fib(3) is the result of fib(2) + fib(1)

// Scala
def fib(i:Int):Int = i match{
    case 0 => 0
    case 1 => 1
    case _ => fib(i-1) + fib(i-2)
}

// Java
public static long itFibN(int n)
{
 if (n < 2)
  return n;
 long ans = 0;
 long n1 = 0;
 long n2 = 1;
 for(n--; n > 0; n--)
 {
  ans = n1 + n2;
  n1 = n2;
  n2 = ans;
 }
 return ans;
}
