Java中的DeskTop类2013-12-05 csdn BruceZhang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:
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 exceptione.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 exceptione.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 exceptione.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 exceptione.printStackTrace();}}}/*** @param args*/public static void main(String[] args) {// TODO Auto-generated method stubbrowse();edit();open();print();}}
