Test if a file is an image file

Question

I am using some file IO and want to know if there is a method to check if a file is an image?

Answer 1

You may try something like this:

String pathname="abc\xyz.png"
File file=new File(pathname);


String mimetype = Files.probeContentType(file.toPath());
//mimetype should be something like "image/png"

if (mimetype != null && mimetype.split("/")[0].equals("image")) {
    System.out.println("it is an image");
}
