Function Parameter and Return
Mapping

JavaFX has ten basic types: Number , Double , Float , Long , Integer , Short ,
Byte , Character , Boolean , and String . The preferred types for normal use are
Number , Integer , Boolean , and String . Unless you have a specific need for the
other types, stick with the preferred types. All these types are represented by cor-
responding Java classes and therefore have access to the corresponding Java
methods available to them. For example, the following illustrates use of the
Character class method, isWhiteSpace() , and the Integer class compareTo()
method.

var aCharacter:Character = 0x20;
println(aCharacter.isWhitespace(aCharacter));

var aInteger:Integer = 1000;
println(aInteger.compareTo(25));

Table 11.1 maps the JavaFX type to its corresponding Java type.
