### Events with Retries and Follow-Ups

The benefit of raising an exception over returning a value will be more evident in the section about Dependencies and Security.

In this example, when the client requests an item by an ID that doesn't exist, raise an exception with a status code of `404`:

     * represents or the drive on which the directory or file resides. Objects
     * other than <code>TYPE_SHARE</code> or <code>TYPE_FILESYSTEM</code> will result
     * in 0L being returned.
     *
     * @return the free disk space in bytes of the drive on which this file or
     *         directory resides
     * @throws CIFSException if an error occurs accessing the resource
     */

    assertEquals(
        "The mean of x and y should equal the mean of y and x", expectedMean, IntMath.mean(y, x));
  }

  /**
   * Computes the mean in a way that is obvious and resilient to overflow by using BigInteger
   * arithmetic.
   */
  private static int computeMeanSafely(int x, int y) {
    BigInteger bigX = BigInteger.valueOf(x);
    BigInteger bigY = BigInteger.valueOf(y);
