JFileChooser

[javabarn]

I am using JFileChooser to open data files I have created but am unable to find a simple explanation as to how to filter them to a specific file extension type. Can anyone help please?

[code]
{File f = new File(thingsName+".zzz");// set to existing file
chooser.setFileSelectionMode(JFileChooser.FILES_ON LY);
chooser.setSelectedFile(f);
int returnVal=chooser.showOpenDialog(null);
File curFile=new File("");
if (returnVal == JFileChooser.APPROVE_OPTION)//file selected
{ curFile = chooser.getSelectedFile();
System.out.println("File Type= "+curFile);}

After very confusing run round the various Sun samples and Definitions found this VERY simple example of how to implement a filter- so simple compared with all the others
Java: javax.swing.filechooser.FileFilter

class SQLfilter extends javax.swing.filechooser.FileFilter {
    public boolean accept(File f) {
        return f.isDirectory() || f.getName().toLowerCase().endsWith(".sql");
    }
    
    public String getDescription() {
        return "SQL files";
    }
}//______________


chooser.setFileFilter(new SQLfilter());
