JavaFX 基础学习二

基本的变量类型 如下： 

 

Type	Declaration	Default Value	Element Specifier	Cardinality	Literal or Creation Examples
String	: String	""	java.lang.String	1 Required	"Brownian"
Integer	: Integer	0	java.lang.Integer	1 Required	1956
Number	: Number	0.0	java.lang.Double	1 Required	1.4142
Boolean	: Boolean	false	java.lang.Boolean	1 Required	true
Duration	: Duration	0ms	javafx.lang.Duration	1 Required	47s
Object	: Object	null	java.lang.Object	0-1 Optional	new Object
other class types	: ClassName	null	ClassName	0-1 Optional	Point {x: 3 y: 9}
function types	: function(name : ParamType, ...) : ReturnType	null	function(name : ParamType, ...) : ReturnType	0-1 Optional	function(x:Integer):String {" {x} "}
sequence types	: ElementSpec[]	[]	ElementSpec	0-n Sequence	[9, 14, 21, 4]

  关键是JavaFX 所以的变量也是走面向对象的路线的，这点和python基本一样
