打开文件
文件选择器可用作打开文件对话框，用于选择单个文件或多个文件，或作为文件保存对话框。以下代码创建一个FileChooser对象并设置其标题，然后显示给用户。
FileChooser fileChooser = new FileChooser();
fileChooser.setTitle("Open Resource File");
fileChooser.showOpenDialog(stage);
可以通过设置initialDirectory和title属性来配置文件选择器对话框窗口。
扩展过滤器
可以设置扩展过滤器来确定在文件选择器中打开哪些文件。
fileChooser.setTitle("View Pictures");fileChooser.setInitialDirectory(new File(System.getProperty("user.home"))); fileChooser.getExtensionFilters().addAll(new FileChooser.ExtensionFilter("All Images", "*.*"),new FileChooser.ExtensionFilter("JPG", "*.jpg"),new FileChooser.ExtensionFilter("GIF", "*.gif"),new FileChooser.ExtensionFilter("BMP", "*.bmp"),new FileChooser.ExtensionFilter("PNG", "*.png"));保存文件
FileChooser API允许用户为由应用程序保存的文件指定文件名及其文件夹。
showSaveDialog方法打开保存对话框窗口。

CSS,Cascading Style Sheets
用于定义界面的显示样式(背景，边框，字体等)
-fx-padding:填充、-fx-font-size：字体大小、-fx-text-fill：文件颜色

MediaView:表示一个播放控件(显示)
Eclpise应用程序的发布
创建一个文件夹，将jdk里的jre拷贝过去
创建启动脚本
IEDA 应用程序的发布
右击项目或模块
open module settings
选择ArtiFacts->JAR->From modules with dependencies
可以选择包含测试类或者不包含
第一个仅导出目标jar包
第二个导出目标jar包和项目所依赖的jar包
选择Include in project build
Build -> Build Artifacts -> Build
构建结果如下：
创建一个文件夹，将jdk里的jre拷贝过去
创建启动脚本
