Show files (Images) in a Java-application

Question

我有一个JPEG文件列表（列出照片），并且希望Windows的默认查看器为该扩展名打开它们，该怎么办？

Answer 1

You can use the java.awt.Desktop class for this:

Desktop.getDesktop().open(new File("image.jpg"));

This will open the image using the default application for opening JPG files on your computer.
