You could just simplify this all to

it == obj

- the only caveat is that if

it

and

obj

are both

null

- you'll get

true

. If that's not desired, then this would yield the same result as the original code

it != null && it == obj

This assumes that

it

and

obj

are of the same type. Using equals allows for a custom comparison function. In this case I have a custom data class which I want to support a comparison to an ID of type Long.

sure, but doesn’t

==

translate to a

.equals()

call in Kotlin?

Yes @Shawn you are correct, in kotlin

a == b

and

a.equals(b)

are identical. @spragg if you want the java "==" you'll have to use === in kotlin.

Nice, yeah it does. @StavFX I only had that second part in to support matching a

null

, and since that is taken care of by what == is translated to. I can do what I need by just having

a == b
