Ignore case for a string in scala

Question

Consider:

object HelloWorld {
  def main(args: Array[String]): Unit = {

    val s:String = "AbcD"

    println(s.contains("ABCD"))
    println(s.contains("AbcD"))

  }
}

Output:

false
true

I need the result to be true in both cases regardless of the case. Is it possible?

Answer 1

If you really need contains use

s.toLowerCase.contains("abcd")

But most likely you are looking for

s.equalsIgnoreCase("abcd")

Answer 2

with Regex

println(s.matches("(?i:.*" + "ABCD" + ".*)"))
