Scala pass input data as arguments

Question

I am trying to write a program to accept 5 employee IDs and the corresponding names and their salaries from the user and store them in three arrays. Pass these arrays to a function display() as arguments. This display() will display the content of the arrays. So i wrote below code, but it showing some error, could you please look into this.

package com.sundogsoftware.spark


object example1 {

  

  def main(args:Array[String]) {

    val id = new Array[Int](5)

    

    for (i <- 0 to 4) {

      id(i) = scala.io.StdIn.readInt()

    }

    



    

    val name = new Array[String](5)

    

    for (i<-0 to 4){  

    name(i) = scala.io.StdIn.readLine()

    }

    


  val salary = new Array[Int](5)


  for (i<-0 to 4){

    salary(i)= scala.io.StdIn.readInt()

  }

  

  

    

 def display(id:Array[Int],name:Array[String],salary:Array[Int]) = {

      

     id.foreach(println)

     name.foreach(println)

     salary.foreach(println)

      

    }   

  

  

  } 

}

Answer 1

Please refer to the below code as per your requirement:

object example1 {

  def main(args:Array[String]) {

    val id = new Array[Int](5)

    println("Enter id")

    for (i <- 0 to 4) {

      id(i) = scala.io.StdIn.readInt()

    }

    val name = new Array[String](5)

    println("Enter name")

    for (i<-0 to 4){

    name(i) = scala.io.StdIn.readLine()

    }

  val salary = new Array[Int](5)

  println("Enter salary")

  for (i<-0 to 4){

    salary(i)= scala.io.StdIn.readInt()

  }

  display(id, name, salary)

   def display(id:Array[Int],name:Array[String],salary:Array[Int]) = {

     id.foreach(println)

     name.foreach(println)

     salary.foreach(println)

    }

  }

}

Hope this helps!
