Kotlin when

// because the other answers didn't show it, you can also do:

val boolA = ....
val boolB = ....

when {
	boolA -> {
    	// stuff
    }
    
    boolB -> {
    	// stuff
    }
}

// for an example, here's something from a libGDX project of mine:
when {
    Gdx.input.isKeyPressed(Input.Keys.W) -> y += getSpeed(diag)
    Gdx.input.isKeyPressed(Input.Keys.S) -> y -= getSpeed(diag)
}
