The if would be here

Question

dewildte · Answer

Have you tried `if object string equals string code `

karelpeeters · Answer

How do you know the strings actually match

HaSH · Answer

< dewildte> I hadn t I just tried now and it appears equals is behaving as expected I honestly thought == and equals would work the same for String Thanks for pointing me towards a solution

karelpeeters · Answer

They are the same

karelpeeters · Answer

in Kotlin at least not in Java

HaSH · Answer

< karelpeeters> I put a few breakpoints in and manually evaluated

HaSH · Answer

< karelpeeters> haha dun dun dun plot thickens

HaSH · Answer

No idea why one works and not the other

karelpeeters · Answer

Can you take a look at the generated bytecode to see what `==` compiles down in your code

karelpeeters · Answer

How did you test equality with the debugger

karelpeeters · Answer

Are you sure you didn t accidentally do `===`

dewildte · Answer

From my limited understanding ` =` and ` string equals ` are not the same

HaSH · Answer

< karelpeeters> I m not sure how to examine the bytecode is it something I can easily see

karelpeeters · Answer

Tools gt Kotlin gt Show generated bytecode

karelpeeters · Answer

and then press decompile to get the Java version of the code

dewildte · Answer

CTRL+A show kotlin byte code

karelpeeters · Answer

< dewildte> Well except for some nullability stuff ` =` and ` equals` are exactly the same

dewildte · Answer

Are they structural or referential

HaSH · Answer

To debug in AS this is a android project I put a break point in AFTER object is instantiated and also on the same line as the if statement If you hover over the var in AS while at a stop point you can look at the underlying data

dewildte · Answer

`===` is referential is it not

HaSH · Answer

So I would know the value of object string before the if code ran

karelpeeters · Answer

Yes kotlin `===` is reference equality so java `==` and kotlin `==` is structural so java ` equals`

dewildte · Answer

Java will give you a warning when trying to compare strings with `==` and ` =` Warning says to use ` equals ` That s why I suggested using it

HaSH · Answer

That show bytecode feature is cool but I don t know how to read bytecode lol

HaSH · Answer

Give me a sec to look

karelpeeters · Answer

That s what the compile button is for simple smile

karelpeeters · Answer

< dewildte> But this is Kotlin

dewildte · Answer

Wibbly wobbly Kotlin javaey stuff

dewildte · Answer

lol

dewildte · Answer

Anyway ` equals ` works for John

dewildte · Answer

I have contributed my piece lol

HaSH · Answer

Seems they call different things in bytecode

dewildte · Answer

AHA

HaSH · Answer

The equals

HaSH · Answer

INVOKEVIRTUAL java lang String equals Ljava lang Object Z

dewildte · Answer

The truth is revealed

HaSH · Answer

The == INVOKESTATIC kotlin jvm internal Intrinsics areEqual Ljava lang Object Ljava lang Object Z

HaSH · Answer

Or am I reading things wrong haha

karelpeeters · Answer

And you ll never guess what the source of that function is like

HaSH · Answer

lol

karelpeeters · Answer

```public static boolean areEqual Object first Object second return first == null second == null first equals second ```

HaSH · Answer

haha

dewildte · Answer

Wow

karelpeeters · Answer

So there must be something else going on

dewildte · Answer

That is casting them as Object but that should not matter

dewildte · Answer

I swear string equality is tricky

HaSH · Answer

I m far from a real programmer but nothing jumps out at me as to why this is happening

karelpeeters · Answer

Would it be possible to create a minimal example we can run

dewildte · Answer

Dude you just compiled byte code How much more real programmer do you need

HaSH · Answer

A job

HaSH · Answer

wink

dewildte · Answer

Lol

HaSH · Answer

Let me see how much code is related to this

dewildte · Answer

I am laughing so hard right now

HaSH · Answer

thumbsup

HaSH · Answer

I think I can get an example made up in a couple mins will post if I can recreate

dewildte · Answer

Cool

HaSH · Answer

Yea of course I can t recreate in a separate project Figures

karelpeeters · Answer

It could be a debugger bug as well

HaSH · Answer

Yea I can t reproduce Figures haha Thanks for the help
