Having default implementation on interface is not appreciated by many developers. We are not going to discuss about the pros and cons, but we are more interested in how Kotlin has achieved this. Note: To keep things simple, the java code blocks used in this article is the decompiled java e...

Achievements are a great way to increase player engagement in our game and give them greater incentives to continue playing. An achievement can represent a player's achievements (for example, number of players defeated or missions completed) or the skills the player has acquired. We can ...
Today, we will be learning how to implement properties in an interface in C#. Interfaces in C# can have many different properties, along with the access modifiers specifying how we should declare property availability within. The interface often acts as a default implementation of different members...
out.println("Interface B"); } @Override public void showC() { System.out.println("Interface C"); } } Output: Interface A Interface B Interface C Interface Extends Multiple Interface in Java An interface can also implement (extend) multiple interfaces. Java allows to interface like class...
Kotlin Data Class Requirements In order to define a class as a data class in Kotlin, it should satisfy the requirements below: The primary constructor should have at least one parameter. Data class cannot be abstract or sealed. Data class can implement interfaces and extend to other classes. ...
using the Fluent API still turns out to be cumbersome and our team considered the option of creating its own DSL. We investigated at what the acceptance route would look like on an external DSL and an internal DSL based on Kotlin (because our product code is written in Java andKotlin). ...
It is true that we should program to interface not implementation, but when we areimplementing an interface, we could leverage some other implementations, here we will usejava.util.Mapto implement our first cache,PerpetualCache: classPerpetualCache:Cache{privatevalcache=HashMap<Any,Any>()overrideval...
Now we have to implement theProcessorinterfacewhich has a unique suspend function that returns an action. TMDApiclass is in charge of making the HTTP request for getting the movies and converting the json response into an array of movies, we don’t care how it is implemented but i...
UX determines whether the user will return to your app or delete it altogether. The role of UI When we talk about interface design, we’re not only talking about buttons and navigation menus. It’s far more than that. User interface enhances the design and appeal of the application and co...
