What are the frameworks supported by Scala?
The frameworks that are supported by Scala are:
What is a scala set?
This is an important scala coding interview question. A Scala set is a collection of components of the same type that are paired together. Both mutable and immutable sets are available in Scala. The mutable set is one in which the object's value is changed, whereas the immutable set is one in which the object's value is not modified. Scala's default settings are immutable.
The Scala.collection.immutable._ package defines the immutable set, while the Scala.collection.changeable._ package defines the mutable set.
Describe how to handle exceptions in Scala.
Scala's exception handling is comparable to Java's, with the distinction that there are no checked exceptions. We can use throw new ExceptionName> to throw exceptions and try{}catch{}blocks to catch them. In the end, there is the last block that is executed. Using case ex: blocks, we can capture several exceptions within the catch block.
What are the many types of Scala literals?
This is an important Scala coding interview question. There are several types of literal in Scala, such as:
In Scala, how do you define a monad?
In Scala, a monad is an object. It aids in the wrapping of another object in accordance with the mini-program, which might be a function to execute data manipulation, especially on the underlying object. It manipulates the object in an indirect manner and selects the method to use for the program on the underlying object.
What are the parameters of the method?
You will often come across this Scala interview question. Method parameters are values that are passed to methods. They are immutable and can only be accessed from within a method. Reference, on the other hand, can be used to access them outside of the mechanism supplied.
In Scala, what are the different sorts of Access Modifiers?
In Scala, there are three different sorts of Access Modifiers: Private, Public, and Protected.
What do you mean by packages in Scala?
In Scala, a package is a container for a collection of classes, subpackages, traits, and package objects. It essentially creates a namespace for us to place our code in multiple files and directories. Packages are a convenient method to organize our code and avoid naming conflicts between members of various packages. Members of packages with access controls such as private, protected, and package specific controlling scope are restricted from accessing other packages, but members with no modifier can be used inside any other package with some reference.
Define Null, Nill, None, and Nothing in Scala?
You will often come across this Scala interview question.
What are the different String Methods?
This is an important Scala coding interview question. There are a number of String Methods. The most common ones are:
The above list of Scala interview questions will be an important part of your scala interview preparation. These Scala interview questions will assist you in solving similar queries or generating new ones. A Scala interview, on the other hand, would not consist solely of these technical Scala interview questions. A Scala interview may also include questions regarding a person's social and life abilities. This allows the recruiter to determine whether the individual can persevere in difficult situations while also assisting their coworkers. As a recruiter, finding someone who gets along with the rest of the team is critical.
