Would you tell me why the output of this code "13579"? Why isn't "02468"?

Question

boolean b = true;
for(int i=0; i<10; i++){
if(b=!b)
System.out.println(i);
}

Answer 1

->Iteration 1:
if(b = !b) <=> if(b = !true) <=> if(b = false) => therefore wont print 0
->Iteration 2:
if(b = !b) <=> if(b = !false) <=> if(b = true) => therefore will print 1
... and so on...
13579

Answer 2

when I=0
b=!b // b=!true so this will be inverterd eg if it is true then changed to false ..false means it will be true...when there is symbol ! like this

so wen it's 0 it's false then I++
now b=!false // now it will be true loop is true now
so it will print 1

then I++ now I=2
now b=!true // changed to false so loops failed

then I++ now I=3
now b=!false // changed to true so loops true
so prints 3

like wise goes on
