How to declare a function argument that can accept any type in Scala

Answer 1

object Main {
  def acceptAnyType(x: Any): Unit = x match {
    case v: Int     => println(s"int: $v")
    case v: Double  => println(s"float: $v")
    case v: String  => println(s"string: $v")
    case v: Boolean => println(s"bool: $v")
    case v: Char    => println(s"char: $v")
    case _          => println("unknown type")
  }

  def main(args: Array[String]): Unit = {
    acceptAnyType(246)
    acceptAnyType(3.14)
    acceptAnyType("ABCD")
    acceptAnyType(true)
    acceptAnyType('A')
  }
}



/*
run:
 
int: 246
float: 3.14
string: ABCD
bool: true
char: A
 
*/
