Adds a ChangeListener which will be notified whenever the value of the ObservableValue changes.

Usage

From source file:Main.java

public static void main(String[] args) {
    IntegerProperty counter = new SimpleIntegerProperty(100);

    // Add a change listener to the counter property
    counter.addListener(Main::changed);

    System.out.println("Before changing the counter value-1");
    counter.set(101);// w ww.j  a  v a 2 s  .  co m
    System.out.println("After changing the counter value-1");

    System.out.println();
    System.out.println("Before changing the counter value-2");
    counter.set(102);
    System.out.println("After changing the counter value-2");

    // Try setting the same value
    System.out.println();
    System.out.println("Before changing the counter value-3");
    counter.set(102); // No change event will be fired.
    System.out.println("After changing the counter value-3");

    // Try setting a different value
    System.out.println();
    System.out.println("Before changing the counter value-4");
    counter.set(103);
    System.out.println("After changing the counter value-4");
}
