    private static final String SRC_FOLDER = "D:/work/java";

    public static void main(String[] args) throws IOException

        File file = new File(SRC_FOLDER);

        DisplayDirectoryStructure displayDirectoryStructure = new DisplayDirectoryStructure();
        displayDirectoryStructure.displayDirStructure(file);

    }

    public void displayDirStructure(File file) throws IOException
    {

        System.out.println("Path = " + file.getAbsolutePath());

        if (file.isDirectory())
        {
            // list all the directory contents
            File files[] = file.listFiles();

            for (File displayFile : files)
            {
                /*
                 * Recursive call.
                 */
                displayDirStructure(displayFile);
            }
        }

    }

}

Output

Path = D:\work\java
Path = D:\work\java\index.html
Path = D:\work\java\jsp
Path = D:\work\java\jsp\async
Path = D:\work\java\jsp\async\async1.jsp
....
