java - Synchronized objects while iterating ArrayList -

let's have following scenario:

final int index = 10; phone phone = phonelist.get(index); synchronized(phone) {    //some code runs here }

so while the phone object (which got throught phonelist.get() method) locked can thread execute method:

phonelist.remove(index);

and null phone object @ given index?

yes. why not?

but still, phone pointing same object. i.e. object gets removed list jvm still has reference it.
