You can also create an environment variable only for a **specific program invocation**, that is only available to that program, and only for its duration.

To do that, create it right before the program itself, on the same line:

<div class="termy">

```console

   * {@code setCount()} to throw an exception, as checking the return value could produce an
   * incorrect error message like "setCount() should return the original count" instead of the
   * message passed to a later invocation of {@code fail()}, like "setCount should throw
   * UnsupportedOperationException."
   */
  abstract void setCountNoCheckReturnValue(E element, int count);
