Setting a path when creating a new File in Java

Question

I currently have the following code:

ImageIO.write(imageBlue, "PNG", new File("c://imageBlue.PNG"));

But I want the program to write it to my Desktop, no matter when Directory I am currently in.

Can you use %userprofile%\\Desktop (when it is windows). Else there is probably a class that will is dependend determine the user home directory — Rik

You can use System.getProperty(String) to get the user.home System Property. Then, use that to get the Desktop. Finally, use that to get your desired output File. Something like,

String homeFldr = System.getProperty("user.home");
File desktop = new File(homeFldr, "Desktop");
ImageIO.write(imageBlue, "PNG", new File(desktop, "imageBlue.PNG"));

Only this configuration needed,

ImageIO.write(imageBlue, "PNG", new File(System.getProperty("user.home") + "/Desktop");

You should change the path of to following :

C:\Users\{your-user-id}\Desktop
