How to get the data type of a variable in Scala

Answer 1

object TypeChecker {
  def main(args: Array[String]): Unit = {
    val n = 345
    val s = "Scala"
    val b = true
    val d = 3.14
    val ch = 'a'

    println(getType(n))  
    println(getType(s)) 
    println(getType(b)) 
    println(getType(d)) 
    println(getType(ch)) 
  }

  def getType(variable: Any): String = {
    variable.getClass.getSimpleName
  }
}
