Java : reading all files

I am attempting to read in files into a java application running via netbeans. I have been successful in previewing the files, but I can only preview .txt files. How can I alter my code to read in any file(s)? (eg. .doc, .docx, .pdf, .jpg, .png).

JFileChooser share = new JFileChooser();
share.showOpenDialog(null);
File f = share.getSelectedFile();
String fileName = f.getAbsolutePath();

    try {
        FileReader reader = new FileReader(fileName);
        BufferedReader br = new BufferedReader(reader);
        jTextArea1.read(br, null);
        br.close();
        jTextArea1.requestFocus();
    }
    catch(Exception e) {
        JOptionPane.showMessageDialog(null, "File not found", "Error", JOptionPane.ERROR_MESSAGE);
    }

you should use something like apache tika

http://tika.apache.org/

this will allow you to read almost any kind of file

also have a look at java.io.File.list() to find out the types of files you have at a location

You can read them alright ; it's just that they are huge blobs of binary data you can't make any sense of without the appropriate tools. Open one of them with a notepad and you'll get what I'm saying.

Their associated software (Word, Reader, etc...) usually do the decoding, but you may find java libraries that can do as much.
