Finding an item that matches predicate in Scala

Question

I\'m trying to search a scala collection for an item in a list that matches some predicate. I don\'t necessarily need the return value, just testing if the list contains it.

Answer 1

Filter and exists keywords to get the matching values from Lists

val values = List(1,2,3,4,5,6,7,8,9,10,....,1000) //List -1
val factors= List(5,7) // List -2

//To get the factors of List-2 from List-1
values .filter(a => factors.exists(b => a%b == 0)) //Apply different logic for our convenience

Given code helps to get the matching values from 2 different lists
