hi guys i know how to print all of array element in one line

val topStudents = arrayOf("Jake", "Jesse", "Matt", "Alec")
names.forEach { println(it) }

but how to do in this condition.

val allStudents = setOf {
      "Michael",
      "Kim",
      topStudents <= i don't know how to retrieve topStudent each names likes "Michael" and "Kim" 
}



// the result what i want is 
val allStudents = setOf {
      "Michael",
      "Kim",
      "Jake",
      "Jesse",
      "Matt",
      "Alec"
}

val topStudents = arrayOf("Jake", "Jesse", "Matt", "Alec")

    val allStudents = setOf(
        "Michael",
        "Kim"
    ) + topStudents.toSet()

    allStudents.forEach { println(it) }

.toSet()

is not necessary for

topStudents

, it can be just

val allStudents = setOf(
        "Michael",
        "Kim"
    ) + topStudents
