Servlet sql delete record

Question

Hi, thanking you in advance for your help. I want to delete a record, but the following code:
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
// TODO Auto-generated method stub
HttpSession session = request.getSession();
String userID = (String)session.getAttribute("edituserID");
response.setContentType("text/html");
PrintWriter pw = response.getWriter();
pw.println("userID is " +userID+ "<br>");
String connectionURL = "jdbc:mysql://localhost/cms_college";
Connection connection=null;
try{
Class.forName("com.mysql.jdbc.Driver");
connection = DriverManager.getConnection(connectionURL, "root", "");
Statement st = connection.createStatement();
st.executeUpdate("DELETE *from users WHERE userID="+"'"+userID+"'" );*
*catch (Exception e){*
*pw.println(e);*
*pw.println("<a href='ListUserServlet.jsp'><br>Deleted</a>");*
gives an error:
userID is 16
com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ' from users WHERE userID='16'' at line 1
Deleted

Thanks matey. You were right. I put a * in where it wasn't needed. It's obvious now, but I just couldn't see it.
