Scala – Iterating a List Collection (Using For Loop)

Here, we will iterate the list collection using the for loop and printed the values of the list collection on the console screen.

Scala code to iterate the list collection using the for loop

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]): Unit = {
        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.
