In this post on Kotlin’s data classes, we’ll take a look at how data classes are better than regular Java POJO (Plain Old Java Object) classes, and how they make our everyday lives easier. We’ll also take a look at some of the caveats of data classes. I’ve also written an a...
#1) Type Inference:In Kotlin, explicit mention of type can be omitted and the Kotlin compiler takes care of assigning an appropriate type to the variable depending on the type of data assignment that’s done. Please note, this is always valid if you still want to explicitly define the type...

An API has been added to kotlin-reflect that can enumerate direct subtypes of a sealed class, namely sealedsubclasses. Automatic mangling is being introduced for names of functions that use inline classes in their signatures. This prevents platform signature crashes when there are several overloads...
It includes classes like buttons, labels, tables, and collection views. Other technologies that are often used in iOS app development include databases (such as SQLite or Core Data), networking libraries (such as AFNetworking or Alamofire), and testing frameworks (such as XCTest or Quick). ...
Chapter 1, Getting Started with Kotlin, covers basic language concepts and syntax, such as types, functions, classes, and flow control structures.Chapter 2, Working with Creational Patterns, explains what classical creational patterns are embedded into the language and how to implement those that ...
In TestNG parallel testing, load testing and dependent testing are possible. It allows the grouping of the test methods into test groups. TestNG supports data-driven testing using the Data providers. Disadvantages A lot of time is consumed to set up TestNG. Also Read: JUnit Vs TestNG: Diff...
Amazon RDS is responsible for hosting the software components and infrastructure of DB instances and DB clusters. You are responsible for query tuning, which is the process of adjusting SQL queries to improve performance. Query performance is highly dependent on database design, data size, data dis...
Other features that are discussed include data classes, lambdas, and inline functions. Procedural programming in Kotlin is covered as well.Chapter 10, Kotlin Programming, contains a step-by-step guide to create a GUI-based desktop application using the JavaFX toolkit. Apache Maven is used to ...
