Program/Source Code:

The source code to read and print the value of the string is given below. The given program is compiled and executed on the ubuntu 18.04 operating system successfully.

// Scala program to read and print the 
// value of string

object Sample{  
    def main(args:Array[String]){  
        var str:String=""
          
        print("Enter string: ")
        str = scala.io.StdIn.readLine()

Enter string: I love my India.
Entered string: I love my India.
