Java ImageIO-相同图像到特定路径

Question

Im implementing a screenshot function and currently it just saves to the project file but it would be nice if it saved to a specific file or location such as the desktop.

Currently:

try {
   imageId = random.nextInt(9999);
   ImageIO.write(MainGame.image, "png" , new File("Sinecure_" + imageId + ".png/"));
   System.out.println("Image Saved as Sinecure_" + imageId);
} catch (IOException e) {
   e.printStackTrace();
}

Answer 1

you can find the user's home directory using this code snippet:

String userHome = System.getProperty( "user.home" );

then you could (depending on the operating system) construct the file path like so:

String fullPath = userHome+File.seperator+"Desktop"+File.seperator+"Sinecure_" + imageId + ".png";
ImageIO.write(MainGame.image, "png" , new File(fullPath));

the above is for windows 7. you will need to adjust for other operating systems, of course. the easiest way to detect what OS youre running under would be another system property:

String OS = System.getProperty("os.name")
