FileFilter for JFileChooser has compilation errors

Question

Eclipse shows two errors:

• The method addChoosableFileFilter in the type JFileChooser is not applicable for the arguments

• Type mismatch: cannot convert from FileNameExtensionFilter to FileFilter whats the error, i cant find it?

JFileChooser chooser = new JFileChooser();
FileFilter filter = new FileNameExtensionFilter("PDF Documents", "pdf");
chooser.addChoosableFileFilter(filter);

Answer 1

The solution is to import javax.swing.filechooser.FileFilter instead of java.io.FileFilter
