How to create an automatic path in a Java application

Question

I am creating a small application to take a screenshot. I can save it automatically on my desktop using this path:

String FILENAME = "C:\\Users\\obed\\Desktop\\" + x + ".png"; ImageIO.write(image, "png", new File(FILENAME)); 

where Obed is my username. How can I automatically change “obed” to a username so that I can run my application on any computer this way?

Answer 1

You can get the user's home directory from the user.home system property:

 String FILENAME = System.getProperty("user.home") + "\\Desktop\\" + x + ".png";
