[dreamtackler]

here is a method i writte in java
public void aaa(){
JFileChooser chooser=new JFileChooser();
chooser.setFileFilter(new FileFilter() {//
setFileFilter(javax.swing.Filechooser.filefilter)
//in javax.swing.JFileChooser can't applied to (<anonymous
java.io.fileFilter>)
public boolean accept(File f) {
String fileName = f.getName().toLowerCase();
return fileName.endsWith(".txt") || f.isDirectory();
}
public String getDescription() {
return "Text Files";
}
});
chooser.showOpenDialog(this);
}

when used in some class it run well.but when it appear in some
class,it goes wrong .the IDE tell me that
setFileFilter(javax.swing.Filechooser.filefilter)
//in javax.swing.JFileChooser can't applied to (<anonymous
java.io.fileFilter>).

Java is case sensitive. FileChooser != filechooser. Probably
filefilter is a local variable in FileChooser, which is unaccessible.
Try javax.swing.filechooser.FileFilter.

Please copy and paste error messages, do not type them by hand. The
error message you give does not make sense.

Read the link in my sig.

I asked you to copy over the ERROR MESSAGE. The above definitely is not
what your compiler or IDE is telling you, or it must be a very bad one.

Did you read the link below? Note that it is very much appreciated here
if at least you try to use proper English.
