public static boolean deleteDirectory(File path) {
        // TODO Auto-generated method stub
        if( path.exists() ) {
            File[] files = path.listFiles();
            for(int i=0; i<files.length; i++) {
                if(files[i].isDirectory()) {
                    deleteDirectory(files[i]);
                }
                else {
                    files[i].delete();
                }
            }
        }
        return(path.delete());
    }

add the code just call it when ever you require using the path of the directory to delete or the file to delete
