Namely fields that are only created once per class and can be accessed without an instance of their containing class. So in this article we will learn how to create static members in kotlin. Kotlin programming language Most of the programming language have concepts where classes can have static members. There will be only single copy of static members whether any number of objects are created. They are associated with the class not with any particular object. Static members are those which are independent of the objects. Submitted by Aman Gautam, on January 29, 2018 In conclusion, if you just need a static field I would suggest to declare the field as const val outside the class to avoid having a companion object and the related inner static class, alternatively just remember to use const inside the companion object to at least avoid the getter method.In this article, we are going to learn how to create static variable and methods in Kotlin? Here is an example: program to count number of objects of a class.

That makes possible to have classes that don’t match the name of the file. So it’s looking better now! Although there is still a companion object, the INNER_STATIC_FIELD now it’s public static final and can be accessed without the companion object instance, which is now completely useless! On the other hand, STATIC_FIELD looks exactly our initial java code: it is defined in a class just as public static final even though the class is not “our” class but MyAwesomeActivityKt.java which is how Kotlin handles having a field declaration outside the MyAwesomeActivity class. If you write Android code, it is very likely that you have some static field to use as key of your Shared Preferences or Bundles and usually in Java they are defined statically: public class MyAwesomeActivity
