We can append or prepend two lists or list&array
Append:

var l = List(1,2,3)    
l = l :+ 4 
Result : 1 2 3 4  
var ar = Array(4, 5, 6)    
for(x <- ar)    
{ l = l :+ x }  
  l.foreach(println)

Result:1 2 3 4 5 6

Prepending:

var l = List[Int]()  
   for(x <- ar)  
    { l= x :: l } //prepending    
     l.foreach(println)   

Result:6 5 4 1 2 3
