Program/Source Code:

The source code to iterate the list collection using the for loop is given below. The given program is compiled and executed on the ubuntu 18.04 operating system successfully.

// Scala program to iterate the list collection 
// using "for" loop

object Sample {  
    def main(args: Array[String]) {  
        var col = List(10,20,30,40,50)         
        for( v <- col){                         
            printf("%d ", v)  
        }  
        println()
    }
}

Output:

10 20 30 40 50

Explanation:

In the above program, we used an object-oriented approach to create the program. We created an object Sample. We defined main() function. The main() function is the entry point for the program.

In the main() function, we created a list collection col. Then we iterate each element of the list collection using the for loop and printed the result on the console screen.
