You can use arrayOf() fuction as it described in Kotlin Basic Type article.
Your code will be the next:
val errorSoon = arrayOf("Hello", "World")

Declare array at global
names = arrayOf(String())
Now in onCreate method Initialize you array with value
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
//Init array here
names = arrayOf("Friends List", "Notification")
}

Please add a short description of how your code answers the question. It would help others understand your answer better.
val array= arrayOf("Hello", "World")
And there is one more way to create String Array.
// Creates an Array<String> with values ["0", "1", "4", "9", "16"]
val asc = Array(5, { i -> (i * i).toString() })

Try this arrayOf() to create array in Kotlin
val errorSoon = arrayOf("a", "b", "c")
to get values from array use below code
for (i in errorSoon.indices) {
print(errorSoon[i]+" ")
}
