Steps

1. How to initialize a Sequence of donuts

The code below shows how to create a Sequence of donuts of type String.

println("Step 1: How to initialize a Sequence of donuts")
val donuts: Seq[String] = Seq("Plain Donut", "Strawberry Donut", "Glazed Donut")
println(s"Elements of donuts = $donuts")

You should see the following output when you run your Scala application in IntelliJ:

Step 1: How to initialize a Sequence of donuts
Elements of donuts = List(Plain Donut, Strawberry Donut, Glazed Donut)

2. How to take the last N elements using the takeRight function

Using the donuts sequence from Step 1, you can use the takeRight method to return a new collection with donut elements consisting of the last N parameter of the take method.

println("\nStep 2: How to take the last N elements using the takeRight function")
println(s"Take the last donut element in the sequence = ${donuts.takeRight(1)}")
println(s"Take the last two donut elements in the sequence = ${donuts.takeRight(2)}")
println(s"Take the last three donut elements in the sequence = ${donuts.takeRight(3)}")

You should see the following output when you run your Scala application in IntelliJ:

Step 2: How to take the last N elements using the takeRight function
Take the last donut element in the sequence = List(Glazed Donut)
Take the last two donut elements in the sequence = List(Strawberry Donut, Glazed Donut)
Take the last three donut elements in the sequence = List(Plain Donut, Strawberry Donut, Glazed Donut)

NOTE:

• If you pass in an integer parameter N to the takeRight method where N is larger than the size of the collection, the takeRight method will return all the elements in the collection.
