[bachtoutou]

Hello evrybody
T want to create a directory which name exists in a JtextField "app" and the path is in a JtextField "mod".This directory is create when i press the button Jbutton2.I have developed a code but it dosen't create anything

private void jButton2_actionPerformed(ActionEvent e) {
File fichier=new File (app.getText());
                        File fichier_parent=new File (mod.getText()); 
                        fichier_parent.mkdirs();
}

What about mkdir() method?

mkdirs is a better method to use, since it will create any parent directories as well.
My guess is there's something wrong with the way the path is specified. Are you sure the complete path is specified?
