Java中的DeskTop类使用介绍
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.
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: package com.brucezhang.desktop; import java.awt.Desktop; import java.io.File; import java.net.URI; public class DeskTopTest { private static Desktop desktop; //使用默认的浏览器打开网页 public static void browse(){ if (Desktop.isDesktopSupported()) { desktop = Desktop.getDesktop(); try { //URI指定网页的地址 desktop.browse(new URI("http://blog.csdn.net/dlutbrucezhang?viewmode=contents")); } catch (Exception e) { // TODO: handle exception e.printStackTrace(); } } } //编辑文件 public static void edit(){ if (Desktop.isDesktopSupported()) { desktop = Desktop.getDesktop(); try { desktop.edit(new File("D:\\BruceZhang.txt")); } catch (Exception e) { // TODO: handle exception e.printStackTrace(); } } } //打开文件,它和编辑文件的过程类似,都是能看到文件的显示 public static void open() { if (Desktop.isDesktopSupported()) { desktop = Desktop.getDesktop(); try { desktop.open(new File("D:\\BruceZhang.txt")); } catch (Exception e) { // TODO: handle exception e.printStackTrace(); } } } //打印指定的文件 public static void print() { if (Desktop.isDesktopSupported()) { desktop = Desktop.getDesktop(); try { desktop.print(new File("D:\\BruceZhang.txt")); } catch (Exception e) { // TODO: handle exception e.printStackTrace(); } } } /** * @param args */ public static void main(String[] args) { // TODO Auto-generated method stub browse(); edit(); open(); print(); } }
