How to identify if the file is an Image (.jpg, .png ...) with Java/JavaFX?
<p>I was searching for how to I can identify or check if the file selected by the user is an Image (eg of extension: .jpg or .png or .bmp and more). <strong>Note that the image is not just one file it's list of images.</strong><br>
I've tried this code:</p>

<pre><code>final File folder = new File( oo );
final File[] listOfFiles = folder.listFiles();
ImageView imageView = new ImageView();
String mimeType = new MimetypesFileTypeMap().getContentType( folder );
String type = mimeType.split( "/" )[0].toLowerCase();
if ( !type.equals( "image" ) ) {
    //TODO
}
else {
    //TODO
}
</code></pre>

<p>After trying that code nothing changed i still get the problem. How i can do so and thanks a lot :-)</p>
