Is it possible to use the content-type of a file to determine its filetype in Java?

Question

If so, how can I do that?

I'm trying to write a method that takes a content-type and returns whether it is a JSON file or not.

Answer 1

Here is a function which takes in a content-type string from an HTTP request and returns TRUE if the content-type was a JSON type or FALSE if it wasn't.

public static boolean isJsonContentType(String contentType) {
    return (contentType.equals("application/json"));
}
