Java calls system default program open

For example, I want to open a PPT file, how to do? The simplest way to call system default is to open PowerPoint.

The Java.awt.Desktop class is used here.

DesktopClass allows a Java application to launch an affiliate application that has been registered on the native desktop to process URI or file.

Supported operations include the following:

• Launches the user's default browser to display the specified URI;
• Launches mailto the user's default mail client with an optional URI;
• Launches the registered application to open, edit, or print the specified file.

Here's a chestnut:

Package Com.sujian;import java.awt.desktop;import java.io.file;import java.io.ioexception;/** * Test open file with default program * * @ Author * @version 1.0, July 9, 2015 */public class Desktoptest {    //the path where the file is located public    static final String path = "d:/ Test.pptx ";    public static void Main (string[] args) {        Desktop desktop = Desktop. Getdesktop ();        File File = new file (PATH);        try {            desktop.open (file);        } catch (IOException e) {            e.printstacktrace ();}}    }
