Does it make a difference if I declare variables inside or outside a loop in Java?

Is this

for(int i = 0; i < 1000; i++) {
   int temporaryValue = someMethod();
   list.add(temporaryValue)
}

equal to this (with respect to memory usage)?

int temporaryValue = 0;
for(int i = 0; i < 1000; i++) {
   temporaryValue = someMethod();
   list.add(temporaryValue)
}

And what if the temporary variable is for example an ArrayList?

for(int i = 0; i < 1000; i++) {
   ArrayList<Integer> array = new ArrayList<Integer>();
   fillArray(array);
   // do something with the array
}
