object PrintArray {
  def main(args: Array[String]): Unit = {
    val words = Array("Scala", "Java", "Python", "C")

    // Print with custom separators and wrappers
    println("Words with custom format:")
    println(words.mkString("[", ", ", "]"))

    // Print each element on a new line using foreach
    println("\nWords (line by line):")
    words.foreach(println)

    // Generic method to print any collection
    def printCollection[T](col: Iterable[T]): Unit = {
      println(col.mkString(", "))
    }

    println("\nGeneric print method:")
    printCollection(words)
  }
}



/*
run:

Words with custom format:
[Scala, Java, Python, C]

Words (line by line):
Scala
Java
Python
C

Generic print method:
Scala, Java, Python, C

*/
