True, but if it's not in the layout, how can it respond?

Carin 7 days ago

But without the button reference, it won't respond at all.

Helaine 12 days ago

I disagree, B makes sense too. The button won't show up.

Carin 18 days ago

I think option C is correct. No response means a crash.

I just hope I remember this for the exam.

Lisha 28 days ago

Right, better to have no response than a crash!

But C is more likely. No response means no crash.

Sherita 1 month ago

True, it might crash if you try to click it.

Cordelia 1 month ago

I feel like option A could happen too.

Dante 2 months ago

Exactly! Without that line, the button is null.

Lisha 2 months ago

Yeah, if the button isn't initialized, it won't respond.

Sherita 2 months ago

I think option C is correct.

Jesusa 2 months ago

But what if the layout loads before the button is initialized?

Lennie 2 months ago

I think it just won't show up in the layout.

Bethanie 2 months ago

Wait, are you saying it crashes? That sounds extreme!

Annalee 3 months ago

Totally agree, the button won't respond at all.

Germaine 3 months ago

If you don't initialize the button, it won't work.

Gertude 3 months ago

I’m pretty confident that if the button isn’t set up properly, it won’t respond when clicked, so I lean towards option C.

Rodrigo 3 months ago

I feel like if the button isn't found, it just won't show up in the layout, which sounds like option B.

Serina 3 months ago

I remember a similar question where not finding a component caused the app to not respond. So, maybe option C could be correct?

Casie 4 months ago

I think if we don't initialize the button, it might lead to a crash when clicked, but I'm not entirely sure.
