    /*
    EXAMPLE FILE FILTER
    */
    ExampleFileFilter filter3 = new ExampleFileFilter();
    filter3.addExtension("wav");
    filter3.setDescription("WAV(*.wav)");
    chooser.setFileFilter(filter3);
    chooser.addChoosableFileFilter(filter3);

    /*
    FILE FILTER CALL
    */
    String extention = chooser.getFileFilter().getExtention();

    that line gives me an error saying
    cannot resolve symbol
    symbol : meathod getExtention()
    location : class javax.swing.filechooser.FileFilter

    String extention = chooser.getFileFilter().getExtention();

    not really. javax.swing.JFileChooser ... but then, you probably have a special setup with "meathods" and what not :) did you try instantiating xFileChoosers, where xFileChooser implements the interface... ? i can't tell anything from that bit of code..


    http://java.sun.com/j2se/1.4.2/docs/api/javax/swing/JFileChooser.html#JFileChooser(javax.swing.filechooser.FileSystemView)

    http://java.sun.com/docs/books/tutorial/uiswing/components/filechooser.html
    + source

    might help..


    edit: dork!

    Of course it doesn't work! You need to cast it to be able to call your methods.

    Use
    String extension = ((ExampleFileFilter)chooser.getFileFilter()).getExtension();
