Usage

From source file:Main.java

public static boolean deleteDir(File dir) {
    if (dir != null && dir.isDirectory()) {
        String[] children = dir.list();
        for (String aChildren : children) {
            boolean success = deleteDir(new File(dir, aChildren));

                return false;
            }/*from w w  w.  j  a v  a2 s  .c  om*/
        }
    }
    // The directory is now empty so delete it
    return dir != null && dir.delete();
}

From source file:FileTableHTML.java

    // Set up an output stream we can print the table to.
    // This is easier than concatenating strings all the time.
    StringWriter sout = new StringWriter();
    PrintWriter out = new PrintWriter(sout);

    // Print the directory name as the page title
    out.println("<H1>" + dirname + "</H1>");

    // Print an "up" link, unless we're already at the root
    String parent = dir.getParent();
    if ((parent != null) && (parent.length() > 0))
        out.println("<A HREF=\"" + parent + "\">Up to parent directory</A><P>");

    // Print out the table
    out.print("<TABLE BORDER=2 WIDTH=600><TR>");
    out.print("<TH>Name</TH><TH>Size</TH><TH>Modified</TH>");
    out.println("<TH>Readable?</TH><TH>Writable?</TH></TR>");

        out.println("<TR><TD>" + (f.isDirectory() ? "<a href=\"" + f + "\">" + entries[i] + "</a>" : entries[i])
                + "</TD><TD>" + f.length() + "</TD><TD>" + new Date(f.lastModified()) + "</TD><TD align=center>"
