Some Important Features of the Kotlin programming language Null safety feature: Another important feature of Kotlin is its null safety feature. In Java, it is possible to create objects that are not valid instances of any class. This can lead to runtime errors if you try to use these invalid objects in your code. Kotlin solves this problem by requiring all variables to be assigned a value before they can be used. This prevents you from creating invalid objects and causing runtime errors

Simplifying finding mistakes and debugging: Kotlin is a programming language that simplifies finding mistakes and debugging.

Kotlin also has a concise and expressive syntax that lets developers write code quickly.

10 Kotlin app development tips you can use to improve your Android applications.

1. Save Memory And Time With Lazy Load Lazy loading is a great way to improve your app's performance. You can save memory and time by deferring the loading of images and other data until needed.

Plus, lazy loading can make your app more responsive and improve the user experience.

2. Reduce the Overall Lines of Code With Lambdas When working on an Android app, one of your main goals should be to reduce the amount of code you write. Lambdas can help you do just that. You can often replace entire lines of code using lambdas with a single function. Not only does this make your code more concise, but it also makes it easier to read and understand.

5. Use Custom Getters and Setters Using custom getters and setters, you can easily manage your data and keep your code clean and organized. This also allows you to control better how your data is accessed and used. You can even use custom getters and setters to create computed properties that are automatically updated when certain values change.

6. Convert Java Code To Kotlin You can use the Kotlin compiler to convert your Java code to Kotlin. Just add the kotlinc directory to your PATH and run the kotlinc command on your .java files.

The compiler will generate .kt files with the same name as the .java files. You can then edit these files and recompile them.

7. Make Validation Easier With An In-Built The Kotlin programming language makes development on Android easier than ever. In addition to being concise and easy to read, Kotlin has great built-in features that can help you validate your code and avoid common mistakes.

8. Make Up For Missing Static Variables With Companion Objects In Kotlin, companion objects are a great way to compensate for the lack of static variables. Companion objects allow you to define properties and methods associated with a class but are not tied to a specific class instance. This makes them perfect for storing values that need to be accessed from anywhere in your code. Plus, companion objects can be used to create singletons, a great way to ensure that only one instance of a particular class exists in your code.

9. Easily Add To The Functionality of A-Class Without Inheriting Features With Extension Inheritance is great for sharing functionality between classes, but sometimes you want to add just a little bit of extra behavior to a class without muddying up the inheritance hierarchy. That's where Kotlin's extensions come in! By using extensions, you can easily add new functionality to a class without inheriting it.

Plus, extensions can be added to any class, even if you don't have the source code!
