val m 1 = List( 1 , 3 , 5 , 2 )
// Applying addString method
val res = m 1 .addString( new StringBuilder(), "*" )
// Displays output
println(res)
}

Output:
1*3*5*2
Example #2:
// Scala program of addString() // method with a separator // Creating object object GfG
{ // Main method
def main(args : Array[String])
{
// Creating a list
val m 1 = List( 1 , 3 , 5 , 2 )
