Scala List concatenation with example
In order to concatenate two lists we need to utilize concat() method in Scala.
Syntax:
List.concat(l1, l2)
In above syntax, l1 is list1 and l2 is list2.
Below is the example to concat two lists in scala.
Example #1:
object GfG
{
def main(args : Array[String])
{
val m 1 = List( 1 , 2 , 3 )
val m 2 = List( 4 , 5 , 6 )
val res = List.concat(m 1 , m 2 )
println(res)
}
}
|
Output:
List(1, 2, 3, 4, 5, 6)
Example #2:
object GfG
{
def main(args : Array[String])
{
val m 1 = List( 1 , 2 , 3 )
val m 2 = List( 3 , 4 , 5 )
val res = List.concat(m 1 , m 2 )
println(res)
}
}
|
Output:
List(1, 2, 3, 3, 4, 5)
Here, the identical elements are not removed.
