Identifying file type in Java

Question

Please help me to find out the type of the file which is being uploaded. I wanted to distinguish between excel type and csv.

MIMEType returns same for both of thes

Answer 1

I hope this will help. Taken from an example not from mine:

import javax.activation.MimetypesFileTypeMap;
import java.io.File;

class GetMimeType {
  public static void main(String args[]) {
    File f = new File("test.gif");
    System.out.println("Mime Type of " + f.getName() + " is " +
                         new MimetypesFileTypeMap().getContentType(f));
    // expected output :
    // "Mime Type of test.gif is image/gif"
  }

}

Same may be true for excel and csv types. Not tested.
