Reading the header of a file in java [closed]

Answer 1

You can try JFileChooser. Here is an example.

import java.io.*;
import javax.swing.*;

class GetFileType {
  public static void main(String[] args){
    JFileChooser chooser = new JFileChooser();
    File file = new File("Hello.txt");

    String fileTypeName = chooser.getTypeDescription(file);
    System.out.println("File Type= "+fileTypeName);
  }
}

This will output Text Document. If it is a MP3 file passed then the output will be MP3 Format Sound.
