I want to bind JavaFX Label.textProperty with int value.
I tried e.g.
Label.textProperty().bindBidirectional(new SimpleIntegerProperty(myInt),
new NumberStringConverter());
or
Label().textProperty().bindBidirectional(new SimpleIntegerProperty(myInt),
new DecimalFormat());
But I always get NullPointerException.
How can I fix it?

Syntax to Initialize JavaFX label is: Label lbl = new Label(); Here, the constructor can be of parameterized and non-parameterized, which depends on the requirement.
You can change the text of a label using its setText() method. This can be done while the application is running. Here is an example of setting the text of a JavaFX Label: label.
A Text is a geometric shape (like a Rectangle or a Circle), while Label is a UI control (like a Button or a CheckBox). In Swing, geometric shapes were restricted to the painting mechanism, while in JavaFX they can be used in more generic ways. And you can use a Text clipping, giving the node shape by the text.
JavaFX properties are often used in conjunction with binding, a powerful mechanism for expressing direct relationships between variables. When objects participate in bindings, changes made to one object will automatically be reflected in another object. This can be useful in a variety of applications.
If you have an int you can create a SimpleIntegerProperty from it and then use the asString() on it :
label.textProperty().bind(new SimpleIntegerProperty(integer).asString());
If you have an IntegerProperty, you can directly use it
label.textProperty().bind(integerProperty.asString());
