How to use a bitwise operator to pass multiple Integer values to a function for Scala

Answer 1

object MultiValueExample {
  val ONE = 0x01
  val TWO = 0x02
  val THREE = 0x04
  val FOUR = 0x08

  def multiValueExample(values: Int): Unit = {
    if ((values & ONE) == ONE) {
      println("ONE")
    }

    if ((values & TWO) == TWO) {
      println("TWO")
    }

    if ((values & THREE) == THREE) {
      println("THREE")
    }

    if ((values & FOUR) == FOUR) {
      println("FOUR")
    }
  }

  def main(args: Array[String]): Unit = {
    multiValueExample(ONE | THREE | FOUR)
  }
}

  
  
/*
run:
    
ONE
THREE
FOUR
