How many collection classes are at the top of the collection library?

How many collection classes are at the top of the collection library?

An immutable collection cannot be updated while a mutable collection can be updated

To update an immutable collection, a new collection is created with the updated values

To update a mutable collection, values are updated in the original collection

What is the difference between an immutable and mutable collection?

What is the difference between an immutable and mutable collection?

Which collection class does not store a single value more than once?

Choose the correct syntax for the `foreach` method.

Choose the correct syntax for the <code>foreach</code> method.

What will be the output of the following code:

```
val array1 = Array(1,2,3,4,5)
val array2 = array1.map(_ * 5)
val finalArray = array2.filter(_ % 2 != 0)
finalArray.foreach(println)
```

What will be the output of the following code:
<pre><code>val array1 = Array(1,2,3,4,5)
val array2 = array1.map(_ * 5)
val finalArray = array2.filter(_ % 2 != 0)
finalArray.foreach(println)
</code></pre>

What will be the output of the following code:

```
val list1 = 39::27::1::83::Nil
val finalList = 5 +: list1
finalList.foreach(println)
```



What will be the output of the following code:
<pre><code>val list1 = 39::27::1::83::Nil
val finalList = 5 +: list1
finalList.foreach(println)
</code></pre>
