Check if array contains substring?

Question

I've got this array:

val array : MutableList<String> =  mutableListOf("laptop on floor", "man is thomas")

How do I check if it contains this string: flo? (It does, in the first element)

Try this code snippet

val array : MutableList<String> =  mutableListOf("laptop on floor", "man is thomas")

val doesContain1 = array.indexOfFirst { it.contains("flo") } >= 0
// or
val doesContain2 = array.find { it.contains("flo") } != null
// or
val doesContain3 = array.any { it.contains("flo") }

Of these three options, the third one, using any, is definitely the most idiomatic.

@Sam yes, but the first two also return some extra result
