Dear all,
could somebody explain me, please, why the output differs for CODE-1 and
CODE-2 see below? I would expect the listener to be called four times in
both cases.
I believe there's trivial answer for that, but I'm not able to find it by
myself, probably due to the hot weather here in Prague, CZ.
Many thanks,
Petr

CODE-1
IntegerProperty property = new SimpleIntegerProperty();
property.addListener((o) -> {
System.out.println("value changed to " + property.get() + " ... " +
System.currentTimeMillis());
});
for (int i = 0; i < 5; i++) {
property.set(i);
}
OUTPUT-1
value changed to 1 ... 1597932211288
value changed to 2 ... 1597932211293
value changed to 3 ... 1597932211293
value changed to 4 ... 1597932211294
***
CODE-2
IntegerProperty property = new SimpleIntegerProperty();
property.addListener((o) -> {
System.out.println("value changed" + " . " + System.currentTimeMillis());
});
for (int i = 0; i < 5; i++) {
property.set(i);
}
OUTPUT-2
value changed ... 1597932237151
