title: Any method to get constant for HTTP GET, POST, PUT, DELETE?
body: <p>For example, <code>HttpServletResponse</code> has the HTTP status codes as constants like</p>
  
  <pre><code>public static final int SC_OK = 200;
  public static final int SC_CREATED = 201;
  public static final int SC_BAD_REQUEST = 400;
  public static final int SC_UNAUTHORIZED = 401;
  public static final int SC_NOT_FOUND = 404;
  </code></pre>
  
  <p>Is there any such constants defined for HTTP methods like <code>GET</code>, <code>POST</code>, ..., anywhere in the Java EE API so that it could be referenced easily, rather than creating one on my own?</p>
