Java中的DeskTop类 (一)

2014-11-24 09:56:20 · 作者: · 浏览: 2

在Jdk1.6以后新增加了一个类--DeskTop,在JDK中它的解释是这样的:


The Desktop class allows a Java application to launch associated applications registered on the native desktop to handle a URI or a file.

Supported operations include:

launching the user-default browser to show a specified URI;
launching the user-default mail client with an optional mailto URI;
launching a registered application to open, edit or print a specified file.
这段话的意思是:
DeskTop类允许一个Java应用程序启动本地的另一个应用程序去处理URI或文件请求,这个类中包含了如下的几个方法:
1.启动用户默认的浏览器显示指定的URI链接
2.启动用户默认的邮件客户端发送URI指定的邮件
3.启动一个注册应用程序(本地安装了的应用程序)去打开,编辑或打印一个指定的文件


下面,给出一段测试代码说明这个类的功能和使用方法,代码中附有注释:
