In this Part of Scala Interview Questions and Answers, we will discuss some tricky Scala Interview Questions with answers. These Scala Interview Questions will help you to crack your Scala Interview. Welcome to this part in the Scala interview questions with answers trilogy.<\/span><\/p>\n<p>So, let&#8217;s start Scala Interview Questions with Answers.<\/p>\n<h3>Scala Interview Questions With Answers<\/h3>\n<p>Below, we are discussing some best Scala Interview Questions with Answers:<\/p>\n<p><strong>Q.1. How is a trait different from an abstract class?<\/strong><\/p>\n<ul>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">A class can inherit from only one <strong><a href=\"https:\/\/data-flair.training\/blogs\/scala-abstract-class\/\">abstract class<\/a><\/strong>, but from multiple traits<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Abstract classes are fully interoperable with <strong><a href=\"https:\/\/data-flair.training\/blogs\/java-tutorial\/\">Java<\/a><\/strong>; traits- only when they hold no implementation code<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Abstract classes can have both- constructor parameters and type parameters; traits only have type parameters<\/span><\/li>\n<\/ul>\n<p><strong>Q.2. How does Scala support both- highly scalable and high-performance applications?<\/strong><\/p>\n<p><span style=\"font-weight: 400\">Not only does Scala use the Actor Concurrency Model, it also supports multi-paradigm programming(object-oriented and functional). This lets us develop highly scalable and high-performance applications.<\/span><\/p>\n<p><strong>Q.3. Differentiate between a Java future and a Scala future.<\/strong><\/p>\n<p><span style=\"font-weight: 400\">There\u2019s one main difference between java.util.concurrent.Future and scala.concurrent.Future. Working with Java\u2019s Future, you must access results using a blocking get() method. With Scala\u2019s future, you can attach callbacks to complete. You can also map it and monadically chain Futures together without blocking. For a Java Future, you can call the method isDone() to confirm whether a Future has completed. This lets you avoid blocking.<\/span><\/p>\n<p><strong>Q.4. Explain the differences between Option, Try, and Either.<\/strong><\/p>\n<p><span style=\"font-weight: 400\">Option, Try, and Either are monads. We can use them to represent computations gone awry. But how are they different? Here we go:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\"><strong><a href=\"https:\/\/data-flair.training\/blogs\/scala-option\/\">Options<\/a><\/strong> denote absence of value. We can use them when we want to perform a search. Example- database access<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Try wraps runtime exceptions. Hence, we can consider it as a monadic approach to the try-catch block in Java.<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Either comes in handy when we must provide more information about the failure of the computation. Eithers have two possible return types- successful\/correct\/expected and the error case.<\/span><\/li>\n<\/ul>\n<p><strong>Q.5. List some advantages of functional programming.<\/strong><\/p>\n<p><span style=\"font-weight: 400\">Functional programming has the following advantages:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Modular<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Easier to test<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Easier to understand<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Supports reuse<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Less prone to bugs<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Supports parallelism and generalization<\/span><\/li>\n<\/ul>\n<p><strong><a href=\"https:\/\/data-flair.training\/blogs\/scala-functions\/\">Read about Scala Functions<\/a><\/strong><\/p>\n<p><strong>Q.6. What is the equivalent type for java.lang.Object here in Scala?<\/strong><\/p>\n<p><span style=\"font-weight: 400\">Where there\u2019s java.lang.Object in Java, we have AnyRef in Scala. This is in context of a Java Runtime Environment (JRE).<\/span><\/p>\n<p><strong><a href=\"https:\/\/data-flair.training\/blogs\/jdk-vs-jre-vs-jvm\/\">Have a look at JRE vs JVM<\/a><\/strong><\/p>\n<p><strong>Q.7. Mention the equivalent construct for Scala\u2019s Option in Java SE 8.<\/strong><\/p>\n<p><span style=\"font-weight: 400\">For<strong> <a href=\"https:\/\/data-flair.training\/blogs\/scala-option\/\">Option in Scala<\/a><\/strong>, we have Optional in Java. This is a class that lets us represent existing or non-existing values. We can access it using the java.util <\/span><span style=\"font-weight: 400\">package.<\/span><\/p>\n<p><span style=\"font-weight: 400\">We can use these constructs to represent optional values. We can also avoid unwanted null checks and NullPointerException.<\/span><\/p>\n<p><strong>Q.8. Define covariance and contravariance.<\/strong><\/p>\n<p><span style=\"font-weight: 400\">A generic type is covariant if it has the same subtype relationship as its type parameter T. It is contravariant when its subtype relationship is in the reverse of that of its type parameter.<\/span><\/p>\n<p><strong>Q.9. Explain the Either\/Left\/Right design pattern in Scala.<\/strong><\/p>\n<p><span style=\"font-weight: 400\">Either is an abstract class. With it, we can represent a value of two possible kinds. The two parameters it takes are Either[A, B]. The two subtypes it has are Left and Right. Left is an instance A and Right is an instance B.<\/span><\/p>\n<p><strong>Q.10. Now, explain the Option\/Some\/None design pattern.<\/strong><\/p>\n<p><span style=\"font-weight: 400\">Option, in Scala, is an abstract class with two subclasses Some and None. Bounded collections like these can hold either one element or none. When it holds one element, it is a Some; otherwise, it is a None. While Some represents an existing value, None represents absence of a value. Here, None is an object and Some is a case class. This also lets us use them in pattern matching.<\/span><\/p>\n<p><span style=\"font-weight: 400\">Together, these definitions form an Option\/Some\/None design pattern in Scala.<\/span><\/p>\n<p><strong>Scala Interview Questions With Answers for Freshers &#8211; Q. 1,2,3,4,5,8,9<\/strong><\/p>\n<p><strong>Scala Interview Questions with Answers for Experienced &#8211; Q. 6,7,10<\/strong><\/p>\n<p><strong>Q.11. List down predefined value types in Scala.<\/strong><\/p>\n<p><span style=\"font-weight: 400\">Scala has 9 predefined, non-nullable value types under AnyVal. These are-<\/span><\/p>\n<p><span style=\"font-weight: 400\">Double, Float, Long, Int, Short, Byte, Unit, Boolean, and Char.<\/span><\/p>\n<p><strong><a href=\"https:\/\/data-flair.training\/blogs\/scala-data-types\/\">Follow the link to learn more about Scala Data Types<\/a><\/strong><\/p>\n<p><strong>Q.12. Which design pattern does pattern matching follow in Scala?<\/strong><\/p>\n<p><span style=\"font-weight: 400\">It follows the Visitor design pattern. It is a behavioral design pattern to help perform an operation on a bunch of similar objects. Another operator that follows this design pattern is Java\u2019s <\/span><i><span style=\"font-weight: 400\">isinstanceof<\/span><\/i><span style=\"font-weight: 400\"> operator.<\/span><\/p>\n<p><strong><a href=\"https:\/\/data-flair.training\/blogs\/scala-pattern-matching\/\">Learn pattern Matching in Scala\u00a0<\/a><\/strong><\/p>\n<p><strong>Q.13. What is a Guard in a for-comprehension?<\/strong><\/p>\n<p><span style=\"font-weight: 400\">When, in a for-comprehension, we want to filter elements, we can use an if-condition. We can call this if-condition a \u2018guard\u2019. When a guard is True, Scala adds that element to a new collection. Otherwise, it performs no operation. Let\u2019s take an example.<\/span><\/p>\n<pre class=\"EnlighterJSRAW\">scala&gt; val nums=List(0,1,2,3,4,5,6,7,8,9,10)\r\nnums: List[Int] = List(0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10)\r\nscala&gt; for(num&lt;-nums if num%3==0) yield num<\/pre>\n<p><span style=\"font-weight: 400\"><strong>res0:<\/strong> List[Int] = List(0, 3, 6, 9)<\/span><\/p>\n<p><span style=\"font-weight: 400\">This code declares a List and adds to another List only those elements which are divisible by 3.<\/span><\/p>\n<p><strong>Q.14. Explain type-casting in Scala.<\/strong><\/p>\n<p><span style=\"font-weight: 400\">We can cast values in an order:<\/span><\/p>\n<p><span style=\"font-weight: 400\">Byte-&gt; Short-&gt; Int-&gt; Long-&gt; Float-&gt; Double<\/span><\/p>\n<p><span style=\"font-weight: 400\">This order is unidirectional; anything else makes the compiler throw an error. It is possible to cast a Char into an Int. It is also possible to cast a <\/span><span style=\"font-weight: 400\">reference type to a subtype.\\<\/span><\/p>\n<p><strong>Q.15. Explain the Diamond Problem.<\/strong><\/p>\n<p><span style=\"font-weight: 400\">This takes us to multiple inheritance. The deadly diamond is when one class extends more than one trait holding the same method.<\/span><\/p>\n<div id=\"attachment_20070\" style=\"width: 230px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2018\/07\/diamond.png\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-20070\" class=\"wp-image-20070 size-full\" src=\"https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2018\/07\/diamond.png\" alt=\"Scala Interview Questions with answers\" width=\"220\" height=\"330\" srcset=\"https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2018\/07\/diamond.png 220w, https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2018\/07\/diamond-100x150.png 100w, https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2018\/07\/diamond-200x300.png 200w\" sizes=\"auto, (max-width: 220px) 100vw, 220px\" \/><\/a><p id=\"caption-attachment-20070\" class=\"wp-caption-text\">Scala Interview Questions with answers &#8211; Dimaond Problem<\/p><\/div>\n<p><span style=\"font-weight: 400\">Scala resolves this by following rules called <\/span><i><span style=\"font-weight: 400\">Class Linearization<\/span><\/i><span style=\"font-weight: 400\">. Let\u2019s take an example.<\/span><\/p>\n<pre class=\"EnlighterJSRAW\">scala&gt; trait A{\r\n    | def show(){\r\n    | println(\"A's show\")\r\n    | }\r\n    | }\r\ndefined trait A\r\nscala&gt; trait B extends A{\r\n    | override def show(){\r\n    | println(\"B's show\")\r\n    | }\r\n    | }\r\ndefined trait B\r\nscala&gt; trait C extends A{\r\n    | override def show(){\r\n    | println(\"C's show\")\r\n    | }\r\n    | }\r\ndefined trait C\r\nscala&gt; class D extends B with C{}\r\ndefined class D\r\nscala&gt; val d=new D()\r\nd: D = D@72d4d9ac\r\nscala&gt; d.show()<\/pre>\n<p><span style=\"font-weight: 400\">C&#8217;s show<\/span><\/p>\n<p><span style=\"font-weight: 400\">As you can see, the compiler prints C\u2019s message. The compiler reads \u201cclass D extends B with C\u201d and reads it right to left. It takes the show() method from the left-most trait, which, to it, is C.<\/span><\/p>\n<p><strong>Q.16. What is a Range?<\/strong><\/p>\n<p><span style=\"font-weight: 400\">Range is a kind of a collection in Scala. It is a lazy collection and we can use it to denote an ordered sequence of Integer values. To use it, we can use the class scala.Range. Here\u2019s an example.<\/span><\/p>\n<pre class=\"EnlighterJSRAW\">scala&gt; 1 to 7<\/pre>\n<p><span style=\"font-weight: 400\"><strong>res4:<\/strong> scala.collection.immutable.Range.Inclusive = Range 1 to 7<\/span><\/p>\n<pre class=\"EnlighterJSRAW\">scala&gt; 1 until 7<\/pre>\n<p><span style=\"font-weight: 400\"><strong>res5:<\/strong> scala.collection.immutable.Range = Range 1 until 7<\/span><\/p>\n<pre class=\"EnlighterJSRAW\">scala&gt; for(i&lt;-1 to 7) println(i)<\/pre>\n<p><span style=\"font-weight: 400\">1<\/span><br \/>\n<span style=\"font-weight: 400\">2<\/span><br \/>\n<span style=\"font-weight: 400\">3<\/span><br \/>\n<span style=\"font-weight: 400\">4<\/span><br \/>\n<span style=\"font-weight: 400\">5<\/span><br \/>\n<span style=\"font-weight: 400\">6<\/span><br \/>\n<span style=\"font-weight: 400\">7<\/span><\/p>\n<p><strong>Q.17. Is it possible to set default values for class parameters?<\/strong><\/p>\n<p><span style=\"font-weight: 400\">When a caller omits a few parameters, Scala will take in the default values if we have provided them. It then becomes optional to include these parameters in a call. It is also possible to provide default values to method parameters.<\/span><\/p>\n<pre class=\"EnlighterJSRAW\">scala&gt; class A(name:String=\"Ayushi\"){}\r\ndefined class A<\/pre>\n<p><strong>Q.18. What do you think is a pure function?<\/strong><\/p>\n<p><span style=\"font-weight: 400\">A pure function has no side-effects. But what does that mean? Well, even if you call it a thousand times, it will return the same outputs for respective inputs.<\/span><br \/>\n<span style=\"font-weight: 400\">* is a pure function with Scala. Let\u2019s see if this always gives us the same result.<\/span><\/p>\n<pre class=\"EnlighterJSRAW\">scala&gt; 3*4<\/pre>\n<p><span style=\"font-weight: 400\"><strong>res8:<\/strong> Int = 12<\/span><\/p>\n<pre class=\"EnlighterJSRAW\">scala&gt; 3*4<\/pre>\n<p><span style=\"font-weight: 400\"><strong>res9:<\/strong> Int = 12<\/span><\/p>\n<pre class=\"EnlighterJSRAW\">scala&gt; 3*4<\/pre>\n<p><span style=\"font-weight: 400\"><strong>res10:<\/strong> Int = 12<\/span><\/p>\n<pre class=\"EnlighterJSRAW\">scala&gt; 1*2<\/pre>\n<p><span style=\"font-weight: 400\"><strong>res11:<\/strong> Int = 2<\/span><\/p>\n<pre class=\"EnlighterJSRAW\">scala&gt; 3*4<\/pre>\n<p><span style=\"font-weight: 400\"><strong>res12:<\/strong> Int = 12<\/span><\/p>\n<p><span style=\"font-weight: 400\">It does. Hence, we conclude what a pure function is.<\/span><\/p>\n<p><a href=\"https:\/\/data-flair.training\/blogs\/scala-currying\/\"><strong>Learn about Scala Currying Functions<\/strong><\/a><\/p>\n<p><strong>Q.19. What are some rules for Scala named arguments?<\/strong><\/p>\n<p><span style=\"font-weight: 400\">There are two rules-<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">You can reorder named arguments<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">For a parameter list with both named and unnamed arguments, the latter must appear first. These should be in order of their parameters in the method signature.<\/span><\/li>\n<\/ul>\n<pre class=\"EnlighterJSRAW\">scala&gt; def show(name:String,surname:String):Unit={\r\n    | println(name+\" \"+surname)\r\n    | }\r\nshow: (name: String, surname: String)Unit\r\nscala&gt; show(\"Ayushi\",surname=\"Sharma\")<\/pre>\n<p>Ayushi Sharma<\/p>\n<p><strong>Q.20. How is a function different from a procedure?<\/strong><\/p>\n<p><span style=\"font-weight: 400\">A function is a computation unit and has no side effects. A procedure is a computation unit too, but has side effects.<\/span><br \/>\n<span style=\"font-weight: 400\">However, both help with computation; this is how they\u2019re similar.<\/span><\/p>\n<p><strong>Scala Interview Questions With Answers for Freshers &#8211; Q. 11,12,13,16,18,19,20<\/strong><\/p>\n<p><strong>Scala Interview Questions with Answers for Experienced &#8211; Q. 14,15,17<\/strong><\/p>\n<p><strong>Q.21. It is impossible to mark constructor parameters as private in Scala?<\/strong><\/p>\n<p><span style=\"font-weight: 400\">No, it isn\u2019t. We can declare a parameter to be private if we declare it without a <\/span><i><span style=\"font-weight: 400\">var<\/span><\/i><span style=\"font-weight: 400\"> or a <\/span><i><span style=\"font-weight: 400\">val<\/span><\/i><span style=\"font-weight: 400\"> keyword. Then, we can only access these values within the class.<\/span><\/p>\n<p><strong><a href=\"https:\/\/data-flair.training\/blogs\/scala-constructor\/\">Read more about Scala constructor<\/a><\/strong><\/p>\n<p><strong>Q.22. We have seen that traits let us implement multiple inheritance. Can traits extend other traits, though?<\/strong><\/p>\n<p><span style=\"font-weight: 400\">Yes, they can. We can extend a trait using the <\/span><i><span style=\"font-weight: 400\">extends<\/span><\/i><span style=\"font-weight: 400\"> keyword. And if we make a class extend it, we can use the keyword <\/span><i><span style=\"font-weight: 400\">override<\/span><\/i><span style=\"font-weight: 400\"> to implement its abstract members.<\/span><\/p>\n<p><strong>Q.23. Mention a way to import all classes from a package.<\/strong><\/p>\n<p><span style=\"font-weight: 400\">While we can import a single class from a package using the dot operator and the name of that class. But to avoid having to name each class that we want to import, we can rather import all classes at once. We use the underscore for this.<\/span><br \/>\n<span style=\"font-weight: 400\">import sound._<\/span><\/p>\n<p><span style=\"font-weight: 400\">This imports all classes. But we can also import some certain classes at once.<\/span><\/p>\n<p><span style=\"font-weight: 400\">import sound.(Treble, Soprano, Bass}<\/span><\/p>\n<p><strong>Q.24. Can classes in Scala extend more than one class?<\/strong><\/p>\n<p><span style=\"font-weight: 400\">A class can extend only one class. So, no, a class cannot extend more than one class. However, it can have many mixins.<\/span><\/p>\n<p><strong>Q.25. Can you Subtype using a trait?<\/strong><\/p>\n<p><span style=\"font-weight: 400\">Absolutely. We can use a subtype of a trait where we need that trait.<\/span><\/p>\n<p><strong>Q.26. So, what is a mixin?<\/strong><\/p>\n<p><span style=\"font-weight: 400\">A <strong><a href=\"https:\/\/data-flair.training\/blogs\/scala-trait-mixins\/\">mixin<\/a><\/strong>, in Scala, is a trait that we can use to compose a class. It is also true that a class can have more than one mixin. To add a mixin to a class, we <\/span><span style=\"font-weight: 400\">use the <\/span><i><span style=\"font-weight: 400\">with<\/span><\/i><span style=\"font-weight: 400\"> keyword as we have seen earlier in our tutorials.<\/span><\/p>\n<p><strong>Q.27. How is nesting functions helpful in Scala?<\/strong><\/p>\n<p><span style=\"font-weight: 400\">When we nest functions, it lets us structure code. This also promotes readability.<\/span><\/p>\n<p><strong>Q.28. What is an abstract type?<\/strong><\/p>\n<p><span style=\"font-weight: 400\">We can use the <\/span><i><span style=\"font-weight: 400\">type<\/span><\/i><span style=\"font-weight: 400\"> keyword to define an abstract type in Scala. This describes element type, but only its implementation defines its actual type.<\/span><\/p>\n<p><strong>Q.29. Explain sealed classes in Scala.<\/strong><\/p>\n<p><span style=\"font-weight: 400\">When we mark a trait or a class as <\/span><i><span style=\"font-weight: 400\">sealed<\/span><\/i><span style=\"font-weight: 400\">, we must declare all subtypes in the same file. This way, we can make sure that we know all subtypes.<\/span><\/p>\n<pre class=\"EnlighterJSRAW\">scala&gt; sealed abstract class Transport\r\ndefined class Transport\r\nscala&gt; case class Scooter() extends Transport\r\ndefined class Scooter\r\nscala&gt; case class Car() extends Transport\r\ndefined class Car\r\nscala&gt; def show(vehicle:Transport):String=vehicle match{\r\n    | case a: Scooter=&gt;\"Two wheels\"\r\n    | case b: Car=&gt;\"Four wheels\"\r\n    | }<\/pre>\n<p><span style=\"font-weight: 400\"><strong>show:<\/strong> (vehicle: Transport)String<\/span><\/p>\n<p><strong>Q.30. Can you reassign parameters for case classes?<\/strong><\/p>\n<p><span style=\"font-weight: 400\">No, we cannot, since case classes help model immutable data. Its parameters are implicitly <\/span><i><span style=\"font-weight: 400\">public val<\/span><\/i><span style=\"font-weight: 400\">.
