scala - Checking if values in List is part of String

Question

I have a string like this:

val a = "some random test message"

I have a list like this:

val keys = List("hi","random","test")

Now, I want to check whether the string a contains any values from keys. How can we do this using the in built library functions of Scala ?

( I know the way of splitting a to List and then do a check with keys list and then find the solution. But I'm looking a way of solving it more simply using standard library functions.)

Answer 1

Something like this?

keys.exists(a.contains(_)) 

Or even more idiomatically

keys.exists(a.contains)
