Program/Source Code:

The source code to store key/value pairs using Map collection is given below. The given program is compiled and executed on the ubuntu 18.04 operating system successfully.

// Scala program to store key/value pairs 
// using Map collection

object Sample {
  // Main method
  def main(args: Array[String]) {
    var students = Map(("101", "Amit"), ("102", "Arun"), ("103", "Anit"))
    var employees = Map((1001, "Akash"), (1002, "Vikas"), (1003, "Prakash"))

    println(students);
    println(employees);
  }
}

Output:

Map(101 -> Amit, 102 -> Arun, 103 -> Anit)
Map(1001 -> Akash, 1002 -> Vikas, 1003 -> Prakash)

Explanation:

Here, we used an object-oriented approach to create the program. And, we also created a singleton object Sample and defined the main() function. The main() function is the entry point for the program.

In the main() function, we created two maps students and employees. The students map contains the student id and student name. The employees map contains employee id and employee name. After that, we printed both maps on the console screen.
