public static void main(String[] args) {
DoubleProperty balance = new SimpleDoubleProperty();
balance.addListener(ov ->
System.out.println(2 + balance.doubleValue()));

balance.set(4.5);
}
}
```
a. The program displays 4.5.
b. The program displays 6.5.
c. The program would display 4.5 if the balance.set(4.5) is placed before the balance.addLisnter(...) statement.
