The source code to merge two integer lists is given below. The given program is compiled and executed on the ubuntu 18.04 operating system successfully.
// Scala program to merge two integer lists
import scala.collection.immutable._
object Sample {
// Main method
def main(args: Array[String]) {
var intList1 = List(0, 1, 2, 3, 4);
var intList2 = List(5, 6, 7, 8, 9);
//Merge two lists
var intList3 = intList1 ++ intList2;
println("List1:");
intList1.foreach((item: Int) => print(item + " "));
println();
println("List2:");
intList2.foreach((item: Int) => print(item + " "));
println();
println("Merged List:");
intList3.foreach((item: Int) => print(item + " "));
println();
}
}
In the above program, we used an object-oriented approach to create the program. Here we imported Collection classes using below statement,
import scala.collection.immutable._
Here, 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 lists intList1, intList2 using List collection. Then we merged intList1 and intList2 using "++" operator. After that, we printed the elements of the merged list on the console screen.
