Print first element in list using Scala

How can I print the first element in list using Scala?

For example in Python I can just write:

>>>l = [1,2,3,4]
>>>one = l[0]
>>>print one

How can I do that on Scala

Thanks.

How do I access elements in Scala list?

We can use the head() and last() methods of the class List to get the first and last elements respectively.

Does Scala list preserve order?

Lists preserve order, can contain duplicates, and are immutable.

What is a SEQ in Scala?

Scala Seq is a trait to represent immutable sequences. This structure provides index based access and various utility methods to find elements, their occurences and subsequences. A Seq maintains the insertion order.

As Hiura said, or like this:

object ListDemo extends App {
    val lst = List(1, 2, 3)
    println(lst(0)) // Prints specific value. In this case 1.
                    // Number at 0 position.
    println(lst(1)) // Prints 2.
    println(lst(2)) // Prints 3.
}
