Change volatile recordings using non-volatile recordings

Question

Are volatile recordings with unstable recordings stored?
For Ex:
I have two streams T1 and T2:

T1:

i = 10;  
volatile boolean result = true;

T2:

while(!result){
}

System.out.println(i);

Does T2 always update the value i (10) or the old value?

Answer 1

Yes. For a volatile operator, there is a relationship between events and events:

Please think about this stackoverflow question: Are volatile variables the variables of previously imposed relationships before they are read?
