Kotlin quiz 3

Which one is wrong?

• var l = [2,4]

• val l = List(2,4)

• val l = listOf(2,4)

• val l = listOf[2,4]

val l = listOf(2,4,6,8)

println(l.indexOf(2))

What is the output?

(a)  

var l = listOf(2,4,6,8)

println(l.asReversed())

What is the output?

• (4,2,8,6)

• (6,4,2,8)

• (8,6,4,2)

• (8,2,6,4)

val list = mutableListOf(1,2,4,5)

list[0] = 50

println(list[0])

• 1

• 50

• error

• indexOutOfBoundException

val list = listOf(2,4,6,8)

list.add(200)

println(list)

Do not use any braces

(a)  

val list = mutableListOf(1,2,3,4,5)

list.add(2,9)

println(list)

• [1, 2, 9, 4, 5]

• error

• [1, 2, 9, 3, 4, 5]

• [1, 9, 3, 4, 5]

val set1 = setOf(1,2,3)

val set2 = setOf(2,3,4)

println(set1.intersect(set2))

• 2,3

• null

• [2,3]

• [1,2,3]

val i = listOf(5,8,7,6)

print(i.contains(5));

what is the output of this code?

(a)  

val list = mutableListOf(1,2,3,4,5,5)

list.removeAll(listOf(2,4))

println(list)

(a)  

val m=listOf(12,6,8,6,7)

print(m.isEmpty())

what is the output of this code?

(a)
