Kotlin: Create a regular array as in Java

For example, in Java I can create such an array with this syntax:

Thing box = new Thing[10];

In Kotlin such syntax can't be used. I would like to create the equivalent of above in Kotlin.

I have found the Array(size: Int, init: Int -> T) methods but it requires that I specify an init lambda that will not allow me to use null. I want to have an array filled with null or some equivalent of the size that I want.

The scenario: I need to have an array of packet handlers where the index of the handler is the packet's opcode.

Use arrayOfNulls(). Naturally, your array will be of nullable type. Alternatively, just use a list.
