Hi,

You can see this example to get more idea of how you can take out the sum of all list of the collection in scala:

scala> val x = (1 to 1000) .toList

It will list down the sum of all the integer and then use the below-given code to take the sum below:

scala> x.reduce(_ + _)

You can see this example and result below:

Hope it helps.
