if (javaClass != other?.javaClass) return false is is equal to if (this.javaClass != other?.javaClass) return false

[snowe]

[snowe]

yes

[snowe]

you can test it using the kotlin repl

[snowe]

class Test {
    fun test(otherClass: Any) {
        if (javaClass != otherClass?.javaClass) println("does not equal")
    }

    fun test2(otherClass: Any) {
        if (this.javaClass != otherClass?.javaClass) println("does not equal")
    }
}

[snowe]

Test().test(Test())

Test().test("")
does not equal

Test().test2("")
does not equal

Test().test2(Test())
