Hi....how to create below equivalent in kotlin public final class Constants {
public static final String TWO_PANE_KEY = "is_two_pane";

private Constants() {

}

public static class DetailActivityKeys {

public static final String STORY_URL_KEY = "storyURL";
public static final String IMAGE_URL_KEY = "imageURL";
public static final String SUMMARY_KEY = "summary";
public static final String TITLE_KEY = "title";

}

public static class API {
public static final String BASE_URL = "https://api.myjson.com/";
}


}

I know I can make on companion class to hold all constants .....but how to group constants in inner classes

[Andreas Sinz]

gauravm: can you give us your kotlin code and what does not work with it?

[gauravm8]

class Constants {

companion object {

val TWO_PANE_KEY = "is_two_pane"

val STORY_URL_KEY = "storyURL"
val IMAGE_URL_KEY = "imageURL"
val SUMMARY_KEY = "summary"
val TITLE_KEY = "title"

val BASE_URL = "https://api.myjson.com/"

}


}

In kotlin i have to make one companion class....but how to make multiple inner static class like behaviour

[gauravm8]

so that each class has its realted constants

[anton.golovin]

you can try class{class{companion}, class{companion}}

[gauravm8]

ahh ok thanks

If you need not instantiate those inner static classes, you can make them nested `object`s in kotlin
