Constants in Kotlin — what's a recommended way to create them?

Question

How is it recommended to create constants in Kotlin? And what\'s the naming convention? I\'ve not found that in the documentation.

companion object {
    //1         


        

Answer 1

If you put your const val valName = valValue before the class name, this way it will creates a

public static final YourClass.Kt that will have the public static final values.

Kotlin:

const val MY_CONST0 = 0
const val MY_CONST1 = 1
data class MyClass(var some: String)

Java decompiled:

public final class MyClassKt {
    public static final int MY_CONST0 = 0;
    public static final int MY_CONST1 = 1;
}
// rest of MyClass.java
