FileFilter for JFileChooser doesn't work

Below is my code to open a JFileChooser on the click of a button. I have created a filter to allow the selection of only .jpg files, but my code doesn't work as expected. All types of files are shown in JFileChooser diaog box. Part of code:

MyFileFilter filter;

fPhoto=new JFileChooser();
fPhoto.setFileSelectionMode(JFileChooser.FILES_AND_DIRECTORIES);        
fPhoto.setFileFilter(filter);

MyFileFilter class:

public class MyFileFilter extends javax.swing.filechooser.FileFilter{

    public boolean accept(File f){

    return f.isDirectory()||(f.isFile()&&f.getName().toLowerCase().endsWith(".jpg"));
    }

    public String getDescription(){

    return ".jpg files";
    }
}
Solution

  • You need to instantiate your filter. Having a null FileFilter will result in no file types being filtered out:

    MyFileFilter filter = new MyFileFilter();
