Kotlin Interview Questions And Answers

Top 5 Technical Interview Questions and Answers for Kotlin Developer jobs:

1.

What is Kotlin and how does it interoperate with Java?

Kotlin is a modern programming language that runs on the JVM (Java Virtual Machine) and can be used anywhere Java is used. It interops with Java seamlessly, meaning you can call Java code from Kotlin and vice versa without any problems. This is crucial in Android development where many libraries are written in Java.

2.

Explain the 'val' and 'var' keywords in Kotlin

In Kotlin, val is used to declare a read-only (final) variable that can be assigned only once. On the other hand, var declares a mutable variable that can be changed after assignment.

3.

What is a data class in Kotlin?

In Kotlin, a data class is used to hold data/state. It automatically generates field getters, setters, equals(), hashCode(), and toString() methods among others. It’s intended to save you boilerplate code for classes that are used to carry data.

4.

Can you explain the difference between '==' and '===' in Kotlin?

'==' is used to compare the values of two objects, while '===' checks for referential equality, meaning it will only return true if both references point to the same object.

5.

What does the ?. operator do in Kotlin?

The ?. operator is known as the safe call operator in Kotlin. It allows you to call a method or access a property of an object that could potentially be null, without causing a NullPointerException.
